Our driver uses devres to manage resources, in particular we call
pcim_enable_device(), what also means we express the intent to get
automatic pci_disable_device() call at driver removal. Manual calls to
pci_disable_device() misuse the API.
Recent commit (see "Fixes" tag) has changed the removal action from
conditional (silent ignore of double call to pci_disable_device()) to
unconditional, but able to catch unwanted redundant calls; see cited
"Fixes" commit for details.
Since that, unloading the driver yields following warn+splat:

When adding a switch filter (such as a MAC or VLAN filter), it is expected
that the driver will detect the case where the filter already exists, and
return -EEXIST. This is used by calling code such as ice_vc_add_mac_addr,
and ice_vsi_add_vlan to avoid incrementing the accounting fields such as
vsi->num_vlan or vf->num_mac.
This logic works correctly for the case where only a single VSI has added a
given switch filter.
When a second VSI adds the same switch filter, the driver converts the
existing filter from an ICE_FWD_TO_VSI filter into an ICE_FWD_TO_VSI_LIST
filter. This saves switch resources, by ensuring that multiple VSIs can
re-use the same filter.
The ice_add_update_vsi_list() function is responsible for doing this
conversion. When first converting a filter from the FWD_TO_VSI into
FWD_TO_VSI_LIST, it checks if the VSI being added is the same as the
existing rule's VSI. In such a case it returns -EEXIST.
However, when the switch rule has already been converted to a
FWD_TO_VSI_LIST, the logic is different. Adding a new VSI in this case just
requires extending the VSI list entry. The logic for checking if the rule
already exists in this case returns 0 instead of -EEXIST.
This breaks the accounting logic mentioned above, so the counters for how
many MAC and VLAN filters exist for a given VF or VSI no longer accurately
reflect the actual count. This breaks other code which relies on these
counts.
In typical usage this primarily affects such filters generally shared by
multiple VSIs such as VLAN 0, or broadcast and multicast MAC addresses.
Fix this by correctly reporting -EEXIST in the case of adding the same VSI
to a switch rule already converted to ICE_FWD_TO_VSI_LIST.

After vsi setup refactor commit 6624e780a577 ("ice: split ice_vsi_setup
into smaller functions") ice_cfg_sw_lldp function which removes rx rule
directing LLDP packets to vsi is moved from ice_vsi_release to
ice_vsi_decfg function. ice_vsi_decfg is used in more cases than just in
vsi_release resulting in unnecessary removal of rx lldp packets handling
switch rule. This leads to lldp packets being dropped after a change number
of channels via ethtool.
This patch moves ice_cfg_sw_lldp function that removes rx lldp sw rule back
to ice_vsi_release function.

The current implementation of pmbus_show_boolean assumes that all devices
support write-back operation of status register to clear pending warnings
or faults. Since clearing individual bits in the status registers was only
introduced in PMBus specification 1.2, this operation may not be supported
by some older devices. This can result in an error while reading boolean
attributes such as temp1_max_alarm.
Fetch PMBus revision supported by the device and modify pmbus_show_boolean
so that it only tries to clear individual status bits if the device is
compliant with PMBus specs >= 1.2. Otherwise clear all fault indicators
on the current page after a fault status was reported.

The panasonic laptop code in various places uses the SINF array with index
values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array
is big enough.
Not all panasonic laptops have this many SINF array entries, for example
the Toughbook CF-18 model only has 10 SINF array entries. So it only
supports the AC+DC brightness entries and mute.
Check that the SINF array has a minimum size which covers all AC+DC
brightness entries and refuse to load if the SINF array is smaller.
For higher SINF indexes hide the sysfs attributes when the SINF array
does not contain an entry for that attribute, avoiding show()/store()
accessing the array out of bounds and add bounds checking to the probe()
and resume() code accessing these.

The PMU driver attempts to use PC_WRITE_RETIRED for the HW branch event,
if enabled. However, PC_WRITE_RETIRED counts only taken branches,
whereas BR_RETIRED counts also non-taken ones.
Furthermore, perf uses HW branch event to calculate branch misses ratio,
implying BR_RETIRED is the correct event to count.
We keep PC_WRITE_RETIRED still as an option in case BR_RETIRED isn't
implemented.

Ido Schimmel says:
====================
Unmask upper DSCP bits - part 4 (last)
tl;dr - This patchset finishes to unmask the upper DSCP bits in the IPv4
flow key in preparation for allowing IPv4 FIB rules to match on DSCP. No
functional changes are expected.
The TOS field in the IPv4 flow key ('flowi4_tos') is used during FIB
lookup to match against the TOS selector in FIB rules and routes.
It is currently impossible for user space to configure FIB rules that
match on the DSCP value as the upper DSCP bits are either masked in the
various call sites that initialize the IPv4 flow key or along the path
to the FIB core.
In preparation for adding a DSCP selector to IPv4 and IPv6 FIB rules, we
need to make sure the entire DSCP value is present in the IPv4 flow key.
This patchset finishes to unmask the upper DSCP bits by adjusting all
the callers of ip_route_output_key() to properly initialize the full
DSCP value in the IPv4 flow key.
No functional changes are expected as commit 1fa3314c14c6 ("ipv4:
Centralize TOS matching") moved the masking of the upper DSCP bits to
the core where 'flowi4_tos' is matched against the TOS selector.

wilc_sdio_probe()
Use devm_clk_get_optional_enabled() instead of devm_clk_get_optional() +
clk_prepare_enable(), which can make the clk consistent with the device
life cycle and reduce the risk of unreleased clk resources. Since the
device framework has automatically released the clk resource, there is
no need to execute clk_disable_unprepare(clk) on the error path, drop
the clk_disable_unprepare label, and the original error process can change
to dispose_irq.

In the `wilc_parse_join_bss_param` function, the TSF field of the `ies`
structure is accessed after the RCU read-side critical section is
unlocked. According to RCU usage rules, this is illegal. Reusing this
pointer can lead to unpredictable behavior, including accessing memory
that has been updated or causing use-after-free issues.
This possible bug was identified using a static analysis tool developed
by myself, specifically designed to detect RCU-related issues.
To address this, the TSF value is now stored in a local variable
`ies_tsf` before the RCU lock is released. The `param->tsf_lo` field is
then assigned using this local variable, ensuring that the TSF value is
safely accessed.

mwifiex_cmd_802_11_scan_ext()
Replace one-element array with a flexible-array member in
`struct host_cmd_ds_802_11_scan_ext`.
With this, fix the following warning:

In spi_geni_remove(), the free_irq() sequence is different from that
on the probe error path. And the IRQ will still remain and it's interrupt
handler may use the dma channel after release dma channel and before free
irq, which is not secure, fix it.

It's important to undo pm_runtime_use_autosuspend() with
pm_runtime_dont_use_autosuspend() at driver exit time unless driver
initially enabled pm_runtime with devm_pm_runtime_enable()
(which handles it for you).
Hence, switch to devm_pm_runtime_enable() to fix it, so the
pm_runtime_disable() in probe error path and remove function
can be removed.

Until VM_DONTEXPAND was added in commit 1c1914d6e8c6 ("dma-buf: heaps:
Don't track CMA dma-buf pages under RssFile") it was possible to obtain
a mapping larger than the buffer size via mremap and bypass the overflow
check in dma_buf_mmap_internal. When using such a mapping to attempt to
fault past the end of the buffer, the CMA heap fault handler also checks
the fault offset against the buffer size, but gets the boundary wrong by
1. Fix the boundary check so that we don't read off the end of the pages
array and insert an arbitrary page in the mapping.
