Merge tag 'drm-misc-next-2021-08-12' of git://anongit.freedesktop.org/drm/drm-misc into drm-next

drm-misc-next for v5.15:

UAPI Changes:

Cross-subsystem Changes:
- Add lockdep_assert(once) helpers.

Core Changes:
- Add lockdep assert to drm_is_current_master_locked.
- Fix typos in dma-buf documentation.
- Mark drm irq midlayer as legacy only.
- Fix GPF in udmabuf_create.
- Rename member to correct value in drm_edid.h

Driver Changes:
- Build fix to make nouveau build with NOUVEAU_BACKLIGHT.
- Add MI101AIT-ICP1, LTTD800480070-L6WWH-RT panels.
- Assorted fixes to bridge/it66121, anx7625.
- Add custom crtc_state to simple helpers, and use it to
  convert pll handling in mgag200 to atomic.
- Convert drivers to use offset-adjusted framebuffer bo mappings.
- Assorted small fixes and fix for a use-after-free in vmwgfx.
- Convert remaining callers of non-legacy drivers to use linux irqs directly.
- Small cleanup in ingenic.
- Small fixes to virtio and ti-sn65dsi86.
