Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

Don't just overwrite the original pointer passed to krealloc()
with its return value without checking latter:
MEM = krealloc(MEM, SZ, GFP);
If krealloc() returns NULL, that erases the pointer
to the still allocated memory, hence leaks this memory.
Instead, use a temporary variable, check it's not NULL
and only then assign it to the original pointer:
TMP = krealloc(MEM, SZ, GFP);
if (!TMP) return;
MEM = TMP;
While on it, use krealloc_array().

The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.
Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.
We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.
This patch was created using:
rg -l drm_atomic_state | \
xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'

The mmap callback reads bo->madv without holding madv_lock, racing with
concurrent DRM_IOCTL_VC4_GEM_MADVISE calls that modify the field under
the same lock. Add the missing locking to prevent the data race.

When vc4_save_hang_state() encounters an early return condition, it
returns without freeing the previously allocated `kernel_state`,
leaking memory.
Add the missing kfree() calls by consolidating the early return paths
into a single place.

The vc4_v3d_bind() function acquires a runtime PM reference via
pm_runtime_resume_and_get() to access V3D registers during setup.
However, this reference is never released after a successful bind.
This prevents the device from ever runtime suspending, since the
reference count never reaches zero.
Release the runtime PM reference by adding pm_runtime_put_autosuspend()
after autosuspend is configured, allowing the device to runtime suspend
after the delay.

The hdmi_colorspace enum was defined to represent the colorspace value
of the HDMI infoframes. It was later used by some HDMI drivers to
express the output format they should be setting up.
During the introduction of the HDMI helpers, it then was used to
represent it in the drm_connector_hdmi_state structure.
However, it's always been somewhat redundant with the DRM_COLOR_FORMAT_*
defines, and now with the drm_output_color_format enum. Let's
consolidate around drm_output_color_format in drm_connector_hdmi_state
to facilitate the current effort to provide a global output format
selection mechanism.

This converts some of the visually simpler cases that have been split
over multiple lines. I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.
Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script. I probably had made it a bit _too_ trivial.
So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.
The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This is the exact same thing as the 'alloc_obj()' version, only much
smaller because there are a lot fewer users of the *alloc_flex()
interface.
As with alloc_obj() version, this was done entirely with mindless brute
force, using the same script, except using 'flex' in the pattern rather
than 'objs*'.

This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:
Single allocations: kmalloc(sizeof(TYPE), ...)
are replaced with: kmalloc_obj(TYPE, ...)
Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with: kmalloc_objs(TYPE, COUNT, ...)
Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...)
(where TYPE may also be *VAR)
The resulting allocations no longer return "void *", instead returning
"TYPE *".

Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.
This lack of consistency cannot be addressed without refactoring the API.
This patch continues the effort to refactor worqueue APIs, which has begun
with the change introducing new workqueues and a new alloc_workqueue flag:
commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")
system_wq should be the per-cpu workqueue, yet in this name nothing makes
that clear, so replace system_wq with system_percpu_wq.
The old wq (system_wq) will be kept for a few release cycles.

The vc4 driver relies on a drm_private_obj, that is initialized by
allocating and initializing a state, and then passing it to
drm_private_obj_init.
Since we're gradually moving away from that pattern to the more
established one relying on a atomic_create_state implementation, let's
migrate this instance to the new pattern.

The IDR interface is deprecated and the XArray API is the recommended
replacement. Replace the per-file IDR used to track perfmons with an
XArray. This allows us to remove the external mutex that protects the
IDR.
While at it, introduce the vc4_perfmon_delete() helper to consolidate
the perfmon cleanup logic used by both vc4_perfmon_close_file() and
vc4_perfmon_destroy_ioctl(). Also, remove the redundant assignment of
vc4file->dev to itself in vc4_perfmon_open_file().

Havign a single set of InfoFrame callbacks doesn't provide enough
information to the DRM framework about the InfoFrame types that are
actually supported. Also it's not really future-proof: it provides a way
to program only a single Vendor-Specific frame, however we might need to
support multiple VSIs at the same time (e.g. HDMI vs HDMI Forum
VSIs).
Provide separate sets of callbacks, one per the InfoFrame type.

Multiple DRM drivers use the pm_runtime_put() return value for printing
debug or even error messages and all of those messages are at least
somewhat misleading.
Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example. It also happens when the kernel
has been configured with CONFIG_PM unset.
For this reason, modify all of those drivers to simply discard the
pm_runtime_put() return value which is what they should be doing.
This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

drm_atomic_get_existing_crtc_state() helper.
This hook is called as part of the global atomic_check, thus before the

`vc4_hdmi_audio_init` calls `devm_snd_dmaengine_pcm_register` which may
return EPROBE_DEFER. Calling `drm_connector_hdmi_audio_init` adds a
child device. The driver model docs[1] state that adding a child device
prior to returning EPROBE_DEFER may result in an infinite loop.

This is the new API for allocating DRM bridges.
This driver already implements refcounting of the struct vc4_dsi, which
embeds struct drm_bridge. Now this is a duplicate of the refcounting
implemented by the DRM bridge core, so convert the vc4_dsi_get/put() calls
into drm_bridge_get/put() calls and get rid of the driver-specific
refcounting implementation.

Some functions used by the HVS->PV muxing tests can return with EDEADLK,
meaning the entire sequence should be restarted. It's not a fatal error
and we should treat it as a recoverable error, and recover, instead of
failing the test like we currently do.

The vc4-pv-muxing-combinations and vc5-pv-muxing-combinations test
suites use a common test init function which, in part, allocates the
drm atomic state the test will use.
That allocation relies on drm_kunit_helper_atomic_state_alloc(), and
thus requires a struct drm_modeset_acquire_ctx. This context will then
be stored in the allocated state->acquire_ctx field.
However, the context is local to the test init function, and is cleared
as soon as drm_kunit_helper_atomic_state_alloc() is done. We thus end up
with an dangling pointer to a cleared context in state->acquire_ctx for
our test to consumes.
We should really allocate the context and the state in the test
functions, so we can also control when we're done with it.

The vc4_mock_atomic_add_output() and vc4_mock_atomic_del_output() assert
that the functions they are calling didn't fail. Since some of them can
return EDEADLK, we can't properly deal with it.
Since both functions are expected to return an int, and all caller check
the return value, let's just properly propagate the errors when they
occur.

The drm_bridge structure contains an encoder pointer that is widely used
by bridge drivers. This pattern is largely documented as deprecated in
other KMS entities for atomic drivers.
However, one of the main use of that pointer is done in attach to just
call drm_bridge_attach on the next bridge to add it to the bridge list.
While this dereferences the bridge->encoder pointer, it's effectively
the same encoder the bridge was being attached to.
We can make it more explicit by adding the encoder the bridge is
attached to to the list of attach parameters. This also removes the need
to dereference bridge->encoder in most drivers.

lockdep complains when a lock is released in a separate thread the
lock is taken in, and it turns out that kunit does run its actions in a

it's supposed to, so let's just get rid of it.
