Pull irq fix from Thomas Gleixner:
"A single fix for the PCI/MSI code:
The conversion to per device MSI domains created a MSI domain with
size 1 instead of sizing it to the maximum possible number of MSI
interrupts for the device. This "worked" as the subsequent allocations
resized the domain, but the recent change to move the prepare() call
into the domain creation path broke this works by chance mechanism.
Size the domain properly at creation time"

When the execution of ath12k_core_hw_group_assign() or
ath12k_core_hw_group_create() fails, the registered notifier chain is not
unregistered properly. Its memory is freed after rmmod, which may trigger
to a use-after-free (UAF) issue if there is a subsequent access to this
notifier chain.
Fixes the issue by calling ath12k_core_panic_notifier_unregister() in

GCC_GCC_PCIE_HOT_RST is wrongly defined for WCN7850, causing kernel crash
on some specific platforms.
Since this register is divergent for WCN7850 and QCN9274, move it to
register table to allow different definitions. Then correct the register
address for WCN7850 to fix this issue.
Note IPQ5332 is not affected as it is not PCIe based device.

Currently to get firmware stats, ath11k_mac_op_get_txpower() calls
ath11k_fw_stats_request() and ath11k_mac_op_sta_statistics() calls
ath11k_mac_get_fw_stats(). Those two helpers are basically doing
the same, except for:
1. ath11k_mac_get_fw_stats() verifies ar->state inside itself.
2. ath11k_mac_get_fw_stats() calls ath11k_mac_fw_stats_request()
which then calls ath11k_mac_fw_stats_reset() to free pdev/vdev
stats whereas only pdev stats are freed by ath11k_fw_stats_request().
3. ath11k_mac_get_fw_stats() waits for ar->fw_stats_complete and
ar->fw_stats_done, whereas ath11k_fw_stats_request() only waits for
ar->fw_stats_complete.
Change to call ath11k_mac_get_fw_stats() in ath11k_mac_op_get_txpower().
This is valid because:
1. ath11k_mac_op_get_txpower() also has the same request on ar->state.
2. it is harmless to call ath11k_fw_stats_vdevs_free() since
ar->fw_stats.vdevs should be empty and there should be no one
expecting it at that time.
3. ath11k_mac_op_get_txpower() only needs pdev stats. For pdev stats,
ar->fw_stats_done is set to true whenever ar->fw_stats_complete is
set to true in ath11k_update_stats_event(). So additional wait on
ar->fw_stats_done does not wast any time.

Currently ath11k_mac_get_fw_stats() is acquiring/releasing ar->conf_mutex by itself.
In order to reuse this function in a context where that lock is already taken, move
lock handling to its callers, then the function itself only has to assert it.
There is only one caller now, i.e., ath11k_mac_op_sta_statistics(), so add lock handling
there.

and commit c3b39553fc77 ("ath11k: add signal report to mac80211 for QCA6390 and WCN6855")
call debugfs functions in mac ops. Those functions are no-ops if CONFIG_ATH11K_DEBUGFS is
not enabled, thus cause wrong status reported.
Move them to mac.c.
Besides, since WMI_REQUEST_RSSI_PER_CHAIN_STAT and WMI_REQUEST_VDEV_STAT stats could also
be requested via mac ops, process them directly in ath11k_update_stats_event().

For WMI_REQUEST_VDEV_STAT request, firmware might split response into
multiple events dut to buffer limit, hence currently in
ath11k_debugfs_fw_stats_process() we wait until all events received.
In case there is no vdev started, this results in that below condition
would never get satisfied
((++ar->fw_stats.num_vdev_recvd) == total_vdevs_started)
finally the requestor would be blocked until wait time out.
The same applies to WMI_REQUEST_BCN_STAT request as well due to:
((++ar->fw_stats.num_bcn_recvd) == ar->num_started_vdevs)
Change to check the number of started vdev first: if it is zero, finish
wait directly; if not, follow the old way.

Currently ath11k_debugfs_fw_stats_process() is using static variables to count
firmware stat events. Taking num_vdev as an example, if for whatever reason (
say ar->num_started_vdevs is 0 or firmware bug etc.) the following condition
(++num_vdev) == total_vdevs_started
is not met, is_end is not set thus num_vdev won't be cleared. Next time when
firmware stats is requested again, even if everything is working fine, we will
fail due to the condition above will never be satisfied.
The same applies to num_bcn as well.
Change to use non-static counters so that we have a chance to clear them each
time firmware stats is requested. Currently only ath11k_fw_stats_request() and
ath11k_debugfs_fw_stats_request() are requesting firmware stats, so clear
counters there.

the wil6210 driver irq handling code is unconditionally writing

In some scenarios, the firmware may be stopped before the interface is
removed, either due to a crash or because the remoteproc (e.g., MPSS)
is shut down early during system reboot or shutdown.
This leads to a delay during interface teardown, as the driver waits for
a vdev delete response that never arrives, eventually timing out.
Example (SNOC):
$ echo stop > /sys/class/remoteproc/remoteproc0/state
[ 71.64] remoteproc remoteproc0: stopped remote processor modem
$ reboot
[ 74.84] ath10k_snoc c800000.wifi: failed to transmit packet, dropping: -108
[ 74.84] ath10k_snoc c800000.wifi: failed to submit frame: -108
[...]
[ 82.39] ath10k_snoc c800000.wifi: Timeout in receiving vdev delete response
To avoid this, skip waiting for the vdev delete response if the firmware is
already marked as unreachable (`ATH10K_FLAG_CRASH_FLUSH`), similar to how
`ath10k_mac_wait_tx_complete()` and `ath10k_vdev_setup_sync()` handle this case.

In ath10k_snoc_hif_stop() we skip disabling the IRQs in the crash
recovery flow, but we still unconditionally call enable again in
ath10k_snoc_hif_start().
We can't check the ATH10K_FLAG_CRASH_FLUSH bit since it is cleared
before hif_start() is called, so instead check the
ATH10K_SNOC_FLAG_RECOVERY flag and skip enabling the IRQs during crash
recovery.
This fixes unbalanced IRQ enable splats that happen after recovering from
a crash.

Make acpi_processor_driver_init() call arch_cpu_rescan_dead_smt_siblings(),
via a new wrapper function called acpi_idle_rescan_dead_smt_siblings(),
after successfully initializing the driver, to allow the "dead" SMT
siblings to go into deep idle states, which is necessary for the
processor to be able to reach deep package C-states (like PC10) going
forward, so that power can be reduced sufficiently in suspend-to-idle,
among other things.
However, do it only if the ACPI idle driver is the current cpuidle
driver (otherwise it is assumed that another cpuidle driver will take
care of this) and avoid doing it on architectures other than x86.

Make intel_idle_init() call arch_cpu_rescan_dead_smt_siblings() after
successfully registering intel_idle as the cpuidle driver so as to
allow the "dead" SMT siblings (if any) to go into deep idle states.
This is necessary for the processor to be able to reach deep package
C-states (like PC10) going forward which is requisite for reducing
power sufficiently in suspend-to-idle, among other things.

Without correct unregisteration, ACPI notify handlers and the platform
drivers installed by generic_subdriver_init() will become dangling
references after removing the loongson_laptop module, triggering various
kernel faults when a hotkey is sent or at kernel shutdown.

loongson_laptop_turn_{on,off}_backlight() are designed for controlling
the power of the backlight, but they aren't really used in the driver
previously.
Unify these two functions since they only differ in arguments passed to
ACPI method, and wire up loongson_laptop_backlight_update() to update
the power state of the backlight as well. Tested on the TongFang L860-T2
Loongson-3A5000 laptop.

Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
Included in here are the following:
- USB offload support for audio devices.
I think this takes the record for the most number of patch series
(30+) over the longest period of time (2+ years) to get merged
properly.
Many props go to Wesley Cheng for seeing this effort through, they
took a major out-of-tree hacked-up-monstrosity that was created by
multiple vendors for their specific devices, got it all merged into
a semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees.
This feature offers major power savings on embedded devices where a
USB audio stream can continue to flow while the rest of the system
is sleeping, something that devices running on battery power really
care about. There are still some more small tweaks left to be done
here, and those patches are still out for review and arguing among
the different hardware companies, but this is a major step forward
and a great example of how to do upstream development well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added
for the USB offload feature.
- lots of little updates and fixes in different drivers
All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues"

It is not necessary to wait until the device_initcall() stage with
intel_idle initialization. All of its dependencies are met after
all subsys_initcall()s have run, so subsys_initcall_sync() can be
used for initializing it.
It is also better to ensure that intel_idle will always initialize
before the ACPI processor driver that uses module_init() for its
initialization.

The kernel robot reported the following errors when the netc-lib driver
was compiled as a loadable module and the enetc-core driver was built-in.
ld.lld: error: undefined symbol: ntmp_init_cbdr
referenced by enetc_cbdr.c:88 (drivers/net/ethernet/freescale/enetc/enetc_cbdr.c:88)
ld.lld: error: undefined symbol: ntmp_free_cbdr
referenced by enetc_cbdr.c:96 (drivers/net/ethernet/freescale/enetc/enetc_cbdr.c:96)
Simply changing "tristate" to "bool" can fix this issue, but considering
that the netc-lib driver needs to support being compiled as a loadable
module and LS1028 does not need the netc-lib driver. Therefore, we add a
boolean symbol 'NXP_NTMP' to enable 'NXP_NETC_LIB' as needed. And when
adding NETC switch driver support in the future, there is no need to
modify the dependency, just select "NXP_NTMP" and "NXP_NETC_LIB" at the
same time.

Previously during driver probe, 1 is unconditionally taken as current
brightness value and set to props.brightness, which will be considered
as the brightness before suspend and restored to EC on resume. Since a
brightness value of 1 almost never matches EC's state on coldboot (my
laptop's EC defaults to 80), this causes surprising changes of screen
brightness on the first time of resume after coldboot.
Let's get brightness from EC and take it as the current brightness on
probe of the laptop driver to avoid the surprising behavior. Tested on
TongFang L860-T2 Loongson-3A5000 laptop.

Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects.

There is no disagreement that we should check both ptp->is_virtual_clock
and ptp->n_vclocks to check if the ptp virtual clock is in use.
However, when we acquire ptp->n_vclocks_mux to read ptp->n_vclocks in
ptp_vclock_in_use(), we observe a recursive lock in the call trace
starting from n_vclocks_store().
============================================
WARNING: possible recursive locking detected
6.15.0-rc6 #1 Not tainted
--------------------------------------------
syz.0.1540/13807 is trying to acquire lock:
ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at:
ptp_vclock_in_use drivers/ptp/ptp_private.h:103 [inline]
ffff888035a24868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at:
ptp_clock_unregister+0x21/0x250 drivers/ptp/ptp_clock.c:415
but task is already holding lock:
ffff888030704868 (&ptp->n_vclocks_mux){+.+.}-{4:4}, at:
n_vclocks_store+0xf1/0x6d0 drivers/ptp/ptp_sysfs.c:215
other info that might help us debug this:
Possible unsafe locking scenario:
CPU0
----
lock(&ptp->n_vclocks_mux);
lock(&ptp->n_vclocks_mux);
*** DEADLOCK ***
....
============================================
The best way to solve this is to remove the logic that checks
ptp->n_vclocks in ptp_vclock_in_use().
The reason why this is appropriate is that any path that uses
ptp->n_vclocks must unconditionally check if ptp->n_vclocks is greater
than 0 before unregistering vclocks, and all functions are already
written this way. And in the function that uses ptp->n_vclocks, we
already get ptp->n_vclocks_mux before unregistering vclocks.
Therefore, we need to remove the redundant check for ptp->n_vclocks in
ptp_vclock_in_use() to prevent recursive locking.

When Linux sends out untagged traffic from a port, it will enter the CPU
port without any VLAN tag, even if the port is a member of a vlan
filtering bridge with a PVID egress untagged VLAN.
This makes the CPU port's PVID take effect, and the PVID's VLAN
table entry controls if the packet will be tagged on egress.
Since commit 45e9d59d3950 ("net: dsa: b53: do not allow to configure
VLAN 0") we remove bridged ports from VLAN 0 when joining or leaving a
VLAN aware bridge. But we also clear the untagged bit, causing untagged
traffic from the controller to become tagged with VID 0 (and priority
0).
Fix this by not touching the untagged map of VLAN 0. Additionally,
always keep the CPU port as a member, as the untag map is only effective
as long as there is at least one member, and we would remove it when
bridging all ports and leaving no standalone ports.
Since Linux (and the switch) treats VLAN 0 tagged traffic like untagged,
the actual impact of this is rather low, but this also prevented earlier
detection of the issue.

Pull power management fixes from Rafael Wysocki:
"Fix three issues introduced into device suspend/resume error paths in
the PM core by some of the recent updates.
First off, replace list_splice() with list_splice_init() in three
places in device suspend error paths to avoid attempting to use an
uninitialized list head going forward.
Second, rearrange device_resume() to avoid leaking the
power.is_suspended device PM flag to the next system suspend/resume
cycle where it can confuse rolling back after an error or early
wakeup.
Finally, add synchronization to dpm_async_resume_children() to avoid
resetting the async state mistakenly for devices whose resume
callbacks have already been queued up for asynchronous execution in
the given device resume phase, which fortunately can happen only if
the preceding system suspend transition has been aborted"
* tag 'pm-6.16-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM: sleep: Add locking to dpm_async_resume_children()
PM: sleep: Fix power.is_suspended cleanup for direct-complete devices
