Hi Linus,
Please, pull the following patches that transform zero-length and
one-element arrays into C99 flexible-array members. These patches
have been baking in linux-next for a while now.
Thanks

Merge tag 'exynos-drm-next-for-v6.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
A patch series for implementing fbdev emulation as in-kernel client.
- This patch series refactors fbdev callbacks to DRM client functions and
simplifies fbdev emulation initialization including some code cleanups.
The changes make fbdev emulation behave like a regular DRM client.

[Why]
After gpu-reset, sometimes the driver fails to enable vblank irq,
causing flip_done timed out and the desktop freezed.
During gpu-reset, we disable and enable vblank irq in dm_suspend() and
dm_resume(). Later on in amdgpu_irq_gpu_reset_resume_helper(), we check
irqs' refcount and decide to enable or disable the irqs again.
However, we have 2 sets of API for controling vblank irq, one is
dm_vblank_get/put() and another is amdgpu_irq_get/put(). Each API has
its own refcount and flag to store the state of vblank irq, and they
are not synchronized.
In drm we use the first API to control vblank irq but in
amdgpu_irq_gpu_reset_resume_helper() we use the second set of API.
The failure happens when vblank irq was enabled by dm_vblank_get()
before gpu-reset, we have vblank->enabled true. However, during
gpu-reset, in amdgpu_irq_gpu_reset_resume_helper() vblank irq's state
checked from amdgpu_irq_update() is DISABLED. So finally it disables
vblank irq again. After gpu-reset, if there is a cursor plane commit,
the driver will try to enable vblank irq by calling drm_vblank_enable(),
but the vblank->enabled is still true, so it fails to turn on vblank
irq and causes flip_done can't be completed in vblank irq handler and
desktop become freezed.
[How]
Combining the 2 vblank control APIs by letting drm's API finally calls
amdgpu_irq's API, so the irq's refcount and state of both APIs can be
synchronized. Also add a check to prevent refcount from being less then
0 in amdgpu_irq_put().
v2:
- Add warning in amdgpu_irq_enable() if the irq is already disabled.
- Call dc_interrupt_set() in dm_set_vblank() to avoid refcount change
if it is in gpu-reset.
v3:
- Improve commit message and code comments.

Commit 41d351f295 ("drm/nouveau: stop using ttm_bo_wait")
converted from ttm_bo_wait_ctx() to dma_resv_wait_timeout().
However, dma_resv_wait_timeout() returns greater than zero on
success as opposed to ttm_bo_wait_ctx(). As a result, relocs
will fail and log errors even when it was a success.
Change the return code handling to match that of
nouveau_gem_ioctl_cpu_prep(), which was already using
dma_resv_wait_timeout() correctly.

During a suspend/resume cycle the VO power domain will be disabled and
the VOP2 registers will reset to their default values. After that the
cached register values will be out of sync and the read/modify/write
operations we do on the window registers will result in bogus values
written. Fix this by re-initializing the register cache each time we
enable the VOP2. With this the VOP2 will show a picture after a
suspend/resume cycle whereas without this the screen stays dark.

Move code from ad-hoc fbdev callbacks into DRM client functions
and remove the old callbacks. The functions instruct the client
to poll for changed output or restore the display. The DRM core
calls both, the old callbacks and the new client helpers, from
the same places. The new functions perform the same operation as
before, so there's no change in functionality.
Replace all code that initializes or releases fbdev emulation
throughout the driver. Instead initialize the fbdev client by a
single call to exynos_fbdev_setup() after exynos has registered its
DRM device. As in most drivers, exynos' fbdev emulation now acts
like a regular DRM client.
The fbdev client setup consists of the initial preparation and the
hot-plugging of the display. The latter creates the fbdev device
and sets up the fbdev framebuffer. The setup performs display
hot-plugging once. If no display can be detected, DRM probe helpers
re-run the detection on each hotplug event.
A call to drm_dev_unregister() releases the client automatically.
No further action is required within exynos. If the fbdev framebuffer
has been fully set up, struct fb_ops.fb_destroy implements the
release. For partially initialized emulation, the fbdev client
reverts the initial setup.

When HuC is loaded by GSC, there is no header definition for the kernel
to look at and firmware is just handed to GSC. However when reading the
version, it should still check the size of the blob to guarantee it's not
incurring into out-of-bounds array access.
If firmware is smaller than expected, the following message is now
printed:
# echo boom > /lib/firmware/i915/dg2_huc_gsc.bin
# dmesg | grep -i huc
[drm] GT0: HuC firmware i915/dg2_huc_gsc.bin: invalid size: 5 < 184
[drm] *ERROR* GT0: HuC firmware i915/dg2_huc_gsc.bin: fetch failed -ENODATA
...
Even without this change the size, header and signature are still
checked by GSC when loading, so this only avoids the out-of-bounds array
access.
