The corresponding allocation is:
> npcm7xx_clk_data = kzalloc(struct_size(npcm7xx_clk_data, hws,

Sometimes Tx is completed immediately after doorbell is updated, which
causes Tx completion routing to update completion bytes before the
same packet bytes are updated in sent bytes in transmit function, hence
hitting BUG_ON() in dql_completed(). To avoid this, update BQL
sent bytes before ringing doorbell.

This code checks "if (parent_hw)" is non-NULL, but then it has more
checks if parent_hw is non-NULL on the lines inside the if statement.
It is a bit confusing.
For the else statement, keep in mind that at the start of the function
we checked:
if (!(parent_name || parent_hw))
return ERR_PTR(-EINVAL);
That check ensures that if parent_hw is NULL that means that parent_name
is non-NULL. At least one must always be non-NULL. So here again, the
checks inside the if statement can be removed.
In the original code, it was a bit confusing and you could easily get
the impression that "init.num_parents" could be zero. When we remove
the unnecessary checking it's more obvious that it's always set to 1.

When CONFIG_OF is disabled then the matching table is not referenced and
the following warning appears:
drivers/clk/ralink/clk-mtmips.c:821:34: warning: unused variable 'mtmips_of_match' [-Wunused-const-variable]
821 | static const struct of_device_id mtmips_of_match[] = {
| ^
There are two match tables in the driver: one for the clock driver and the
other for the reset driver. The only difference between them is that the
clock driver uses 'data' and does not have 'ralink,rt2880-reset' compatible.
Both just can be merged into a single one just by adding the compatible
'ralink,rt2880-reset' entry to 'mtmips_of_match[]', which will allow it to
be used for 'mtmips_clk_driver' (which doesn't use the data) as well as for
'mtmips_clk_init()' (which doesn't need get called for 'ralink,rt2880-reset').
Doing in this way ensures that 'CONFIG_OF' is not disabled anymore so the
above warning disapears.

It may happen that the work to destroy a queue
(for example nvmet_tcp_release_queue_work()) is started while
an auth-send or auth-receive command is still completing.
nvmet_sq_destroy() will block, waiting for all the references
to the sq to be dropped, the last reference is then
dropped when nvmet_req_complete() is called.
When this happens, both nvmet_sq_destroy() and
nvmet_execute_auth_send()/_receive() will free the dhchap pointers by
calling nvmet_auth_sq_free().
Since there isn't any lock, the two threads may race against each other,
causing double frees and memory corruptions, as reported by KASAN.

The function vp_modern_map_capability() takes the size parameter,
which corresponds to the size of virtio_pci_common_cfg. As a result,
this indicates the size of memory area to map.
Now the size is the size of virtio_pci_common_cfg, but some feature(such
as the _F_RING_RESET) needs the virtio_pci_modern_common_cfg, so this
commit changes the size to the size of virtio_pci_modern_common_cfg.

Commit e2ae38cf3d91 ("vhost: fix hung thread due to erroneous iotlb
entries") Forbade vhost iotlb msg with null size to prevent entries
with size = start = 0 and last = ULONG_MAX to end up in the iotlb.
Then commit 95932ab2ea07 ("vhost: allow batching hint without size")
only applied the check for VHOST_IOTLB_UPDATE and VHOST_IOTLB_INVALIDATE
message types to fix a regression observed with batching hit.
Still, the introduction of that check introduced a regression for
some users attempting to invalidate the whole ULONG_MAX range by
setting the size to 0. This is the case with qemu/smmuv3/vhost
integration which does not work anymore. It Looks safe to partially
revert the original commit and allow VHOST_IOTLB_INVALIDATE messages
with null size. vhost_iotlb_del_range() will compute a correct end

A firmware error is triggered when configuring a 9k MTU on the PF after
switching to switchdev mode and then using a vdpa device with larger
(1k) rings:
mlx5_cmd_out_err: CREATE_GENERAL_OBJECT(0xa00) op_mod(0xd) failed, status bad resource(0x5), syndrome (0xf6db90), err(-22)
This is due to the fact that the hw VQ size parameters are computed
based on the umem_1/2/3_buffer_param_a/b capabilities and all
device capabilities are read only when the driver is moved to switchdev mode.
The problematic configuration flow looks like this:
1) Create VF
2) Unbind VF
3) Switch PF to switchdev mode.
4) Bind VF
5) Set PF MTU to 9k
6) create vDPA device
7) Start VM with vDPA device and 1K queue size
Note that setting the MTU before step 3) doesn't trigger this issue.
This patch reads the forementioned umem parameters at the latest point
possible before the VQs of the device are created.
v2:
- Allocate output with kmalloc to reduce stack frame size.
- Removed stable from cc.

This patch fixes the issue by always clearing the debugfs entry in
mlx5_vdpa_remove_debugfs. Also, stop removing the debugfs entry in
.dev_del op: the debugfs entry is already handled within the
setup_driver/teardown_driver scope.

With the recent removal of vm_dev from devres its memory is only freed
via the callback virtio_mmio_release_dev. However, this only takes
effect after device_add is called by register_virtio_device. Until then
it's an unmanaged resource and must be explicitly freed on error exit.
This bug was discovered and resolved using Coverity Static Analysis
Security Testing (SAST) by Synopsys, Inc.

https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers
Qualcomm driver updates for v6.7
This introduces partial support for the Qualcomm Secure Execution
Environment SCM interface, and uses this to implement EFI variable
access on the Windows On Snapdragon devices (for now).
The 32/64-bit calling convention detector of the SCM interface is
updated to not choose 64-bit convention when Linux is 32-bit. The
"extern" specifier is dropped from the interface include file.
The LLCC driver gains support for carrying configuration for multiple
different system/DDR configurations for a given platform, and selecting
between them. Support for Q[DR]U1000 is added to the driver.
All exported symbols are transitioned to EXPORT_SYMBOL_GPL().
The platform_drivers in the Qualcomm SoC are transitioned to the
void-returning remove_new implementation.
The rmtfs memory driver gains support for leaving guard pages around the
used area, to avoid issues if the allocation happens to be placed
adjacent to another protected memory region.
The socinfo driver gains knowledge about IPQ8174, QCM6490, SM7150P and
various PMICs used together with SM8550.

have 0xffff, hard code this for all MMIO gmux's so they all have the

fails
If platform_profile_register() fails, the driver does not propagate
the error, but instead probes successfully. This means when the driver
unbinds, the a warning might be issued by platform_profile_remove().
Fix this by propagating the error back to the caller of
surface_platform_profile_probe().
Compile-tested only.

Due to the initial confusion about MIPI_DSI_MODE_EOT_PACKET, properly
renamed to MIPI_DSI_MODE_NO_EOT_PACKET, reflecting its actual meaning,
both the DSI_TXRX_CON register setting for bit (HSTX_)DIS_EOT and the
later calculation for horizontal sync-active (HSA), back (HBP) and
front (HFP) porches got incorrect due to the logic being inverted.
This means that a number of settings were wrong because....:
- DSI_TXRX_CON register setting: bit (HSTX_)DIS_EOT should be
set in order to disable the End of Transmission packet;
- Horizontal Sync and Back/Front porches: The delta used to
calculate all of HSA, HBP and HFP should account for the
additional EOT packet.
Before this change...
- Bit (HSTX_)DIS_EOT was being set when EOT packet was enabled;
- For HSA/HBP/HFP delta... all three were wrong, as words were
added when EOT disabled, instead of when EOT packet enabled!
Invert the logic around flag MIPI_DSI_MODE_NO_EOT_PACKET in the
MediaTek DSI driver to fix the aforementioned issues.

acpi_agdi_init() in acpi_arm_init() will register a SDEI event, so
it needs the SDEI subsystem to be initialized (which is done in
acpi_ghes_init()) before the AGDI driver probing.
In commit fcea0ccf4fd7 ("ACPI: bus: Consolidate all arm specific
initialisation into acpi_arm_init()"), the acpi_agdi_init() was
called before acpi_ghes_init() and it causes following failure:
| [ 0.515864] sdei: Failed to create event 1073741825: -5
| [ 0.515866] agdi agdi.0: Failed to register for SDEI event 1073741825
| [ 0.515867] agdi: probe of agdi.0 failed with error -5
| ...
| [ 0.516022] sdei: SDEIv1.0 (0x0) detected in firmware.
Fix it by moving acpi_arm_init() to the place of after
acpi_ghes_init().

```

Furthermore, when shutting down with `poweroff` and modem attached, the
system rebooted instead of powering down as expected. The modem works
again only after power cycling.
