This is a follow up to commit c4781dc3d1cf ("Kbuild: enable
-fms-extensions") but in a separate change due to being substantially
different from the initial submission.
There are many places within the kernel that use their own CFLAGS
instead of the main KBUILD_CFLAGS, meaning code written with the main
kernel's use of '-fms-extensions' in mind that may be tangentially
included in these areas will result in "error: declaration does not
declare anything" messages from the compiler.
Add '-fms-extensions' to all these areas to ensure consistency, along
with -Wno-microsoft-anon-tag to silence clang's warning about use of the
extension that the kernel cares about using. parisc does not build with
clang so it does not need this warning flag. LoongArch does not need it
either because -W flags from KBUILD_FLAGS are pulled into cflags-vdso.

This enables QoS configuration for QNOC type device which can be found
on SA8775P platform. It enables QoS configuration for master ports with
predefined priority and urgency forwarding. This helps in prioritizing
the traffic originating from different interconnect masters at NOC.
The system may function normally without this feature. However, enabling
QoS helps optimize latency and bandwidth across subsystems like CPU, GPU,
and multimedia engines, which becomes important in high-throughput
scenarios. This is a feature aimed at performance enhancement to improve
system performance under concurrent workloads.

Drop the QPIC interconnect and BCM nodes for the SDX75 SoC. The reason
is that this QPIC BCM resource is already defined as a RPMh clock in
clk-rpmh driver as like other SDX SoCs. So it is wrong to describe the
same resource in two different providers.
Also, without this series, the NAND driver fails to probe on SDX75 as
the interconnect sync state disables the QPIC nodes as there were no
clients voting for this ICC resource. However, the NAND driver had already
voted for this BCM resource through the clk-rpmh driver. Since both votes
come from Linux, RPMh was unable to distinguish between these two and ends
up disabling the resource during sync state.

The lack of the interconnects for the USB2 host might result in the

locking up, resulting in -EBUSY errors for the USB host on the platform.

The icc_commit_set() function, used by the debugfs interface, checks
the validity of the global cur_path pointer using IS_ERR_OR_NULL().
However, in the specific case where cur_path is NULL, while
IS_ERR_OR_NULL(NULL) correctly evaluates to true, the subsequent call
to PTR_ERR(NULL) returns 0.
This causes the function to return a success code (0) instead of an
error, misleading the user into believing their bandwidth request was
successfully committed when, in fact, no operation was performed.
Fix this by adding an explicit check to return -EINVAL if cur_path is
NULL. This prevents silent failures and ensures that an invalid
operational sequence is immediately and clearly reported as an error.

As like other SDX SoCs, SDX75 SoC's QPIC BCM resource was modeled as a
RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also
described as an interconnect and BCM node mistakenly. It is incorrect to
describe the same resource in two different providers, as it will lead to
votes from clients overriding each other.
Hence, drop the QPIC interconnect and BCM nodes and let the clients use
clk-rpmh driver to vote for this resource.
Without this change, the NAND driver fails to probe on SDX75, as the
interconnect sync state disables the QPIC nodes as there were no clients
voting for this ICC resource. However, the NAND driver had already voted
for this BCM resource through the clk-rpmh driver. Since both votes come
from Linux, RPMh was unable to distinguish between these two and ends up
disabling the QPIC resource during sync state.

During scan and remain-on-channel requests, a scan link vif (arvif) is
assigned and a temporary vdev is created. If vdev creation fails, the
assigned arvif is left attached until the virtual interface is removed,
leaving a stale link in ahvif.
Fix this by freeing the stale arvif and resetting the corresponding link in
ahvif by calling ath12k_mac_unassign_link_vif() when vdev creation fails.
While at it, propagate the actual error code from ath12k_mac_vdev_create()
instead of returning -EINVAL in ath12k_mac_initiate_hw_scan().

Currently, vdev limit check is performed only in
ath12k_mac_assign_vif_to_vdev(). If the host has already created
maximum number of vdevs for the radio (ar) and a scan request
arrives for the same radio, ath12k_mac_initiate_hw_scan() attempts
to create a vdev without checking the limit, causing firmware asserts.
Centralize the vdev limit guard by moving the check into
ath12k_mac_vdev_create() so that all callers obey the limit.
While doing this, update the condition from
`num_created_vdevs > (TARGET_NUM_VDEVS(ab) - 1)` to
`num_created_vdevs >= TARGET_NUM_VDEVS(ab)` for clarity and to
eliminate unnecessary arithmetic.

During firmware recovery or suspend/resume, m3 memory could be reused if
the size of the new m3 binary is equal to or less than that of the
existing memory. There will be issues for the latter case, since
m3_mem->size will be updated with a smaller value and this value is
eventually used in the free path, where the original total size should be
used instead.
To fix it, add a new member in m3_mem_region structure to track the original
memory size and use it in free path.

Rename drm_client_framebuffer_create() to drm_client_buffer_create_dump()
and adapt callers. The new name reflects the function's purpose. Using
dumb buffers is the easiest way for creating a GEM buffer in a drivers-
independent way.
There's also drm_client_buffer_create(), which creates the client buffer
from a preexisting buffer object. This helper can be exported for drivers
that create their own GEM buffer object.

The client buffer's framebuffer holds a reference and pointer on
each of its GEM buffer objects. Thus the field gem in the client-
buffer struct is not necessary. Deprecated the field and convert
the client-buffer helpers to use the framebuffer's objects.
In drm_client_buffer_delete(), do a possible vunmap before releasing
the framebuffer. Otherwise we'd eventually release the framebuffer
before unmaping its buffer objects.

Creating and deleting a client buffer always creates and deletes
the underlying DRM framebuffer. Inline the helper functions into
their callers.
With the _addfb code being inlined into drm_client_buffer_create(),
clean up the function's error rollback to release the framebuffer's
handle and GEM buffer object as needed.
Move the _rmfb code into drm_client_buffer_delete() rather than its
current location in drm_client_framebuffer_delete(). The former is
now the inverse of drm_client_buffer_create(). Makes no difference
for cleaning up. Also prepares for the removal of
drm_client_framebuffer_delete().

across drm_client_buffer_create() and drm_client_framebuffer_create().
Put all dumb-buffer code into drm_client_framebuffer_create() and leave

Apart form the architectural improvements, drm_client_buffer_create()
can now be exported if needed by clients. The client will be able to

After studying the linuwu_sense driver
(https://github.com/0x7375646F/Linuwu-Sense) i was able to understand
the meaning of the SetGamingFanBehavior() WMI method:
- the first 16-bit are a bitmap of all fans affected by a fan behavior
change request.
- the next 8 bits contain four fan mode fields (2-bit), each being
associated with a bit inside the fan bitmap.
There are three fan modes: auto, turbo and custom.
Use this newfound knowledge to fix the turbo fan handling by setting
the correct bits before calling SetGamingFanBehavior(). Also check
the result of the WMI method call and return an error should the ACPI
firmware signal failure.

This is the new API for allocating DRM bridges.
This conversion was missed during the initial conversion of all bridges to
the new API. Thus all kernels with commit 94d50c1a2ca3 ("drm/bridge:
get/put the bridge reference in drm_bridge_attach/detach()") and using this
driver now warn due to drm_bridge_attach() incrementing the refcount, which
is not initialized without using devm_drm_bridge_alloc() for allocation.
To make the conversion simple and straightforward without messing up with
the drmm_simple_encoder_alloc(), move the struct drm_bridge from struct
imx_parallel_display_encoder to struct imx_parallel_display.
Also remove the 'struct imx_parallel_display *pd' from struct
imx_parallel_display_encoder, not needed anymore.
