Merge tag 'drm-fixes-2023-02-17' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie: "Just a final collection of misc fixes, the biggest disables the recently added dynamic debugging support, it has a regression that needs some bigger fixes. Otherwise a bunch of fixes across the board, vc4, amdgpu and vmwgfx mostly, with some smaller i915 and ast fixes. drm: - dynamic debug disable for now fbdev: - deferred i/o device close fix amdgpu: - Fix GC11.x suspend warning - Fix display warning vc4: - YUV planes fix - hdmi display fix - crtc reduced blanking fix ast: - fix start address computation vmwgfx: - fix bo/handle races i915: - gen11 WA fix" * tag 'drm-fixes-2023-02-17' of git://anongit.freedesktop.org/drm/drm: drm/amd/display: Fail atomic_check early on normalize_zpos error drm/amd/amdgpu: fix warning during suspend drm/vmwgfx: Do not drop the reference to the handle too soon drm/vmwgfx: Stop accessing buffer objects which failed init drm/i915/gen11: Wa_1408615072/Wa_1407596294 should be on GT list drm: Disable dynamic debug as broken drm/ast: Fix start address computation fbdev: Fix invalid page access after closing deferred I/O devices drm/vc4: crtc: Increase setup cost in core clock calculation to handle extreme reduced blanking drm/vc4: hdmi: Always enable GCP with AVMUTE cleared drm/vc4: Fix YUV plane handling when planes are in different buffers
