  - drm: rework SET_MASTER and DROP_MASTER perm handling

Cross-subsystem Changes:

  - mm: export two symbols from slub/slob
  - fbdev: savage: fix -Wextra build warning
  - video: omap2: Use scnprintf() for avoiding potential buffer overflow

Core Changes:

  - Remove drm_pci.h
  - drm_pci_{alloc/free)() are now legacy
  - Introduce managed DRM resourcesA
  - Allow drivers to subclass struct drm_framebuffer
  - Introduce struct drm_afbc_framebuffer and helpers

  - Introduce simple-encoder helper
  - vram-helpers: set fence on plane
  - dp_mst: ACT timeout improvements
  - dp_mst: Remove drm_dp_mst_has_audio()
  - TTM: ttm_trace_dma_{map/unmap}() cleanups
  - dma-buf: add flag for PCIP2P support
  - EDID: Various improvements
  - Encoder: cleanup semantics of possible_clones and possible_crtcs

  - Writeback documentation updates

Driver Changes:

  - Convert several drivers to i2c_new_client_device()
  - Drop explicit drm_mode_config_cleanup() calls from drivers
  - Auto-release device structures with drmm_add_final_kfree()
  - Init bfdev console after registering DRM device
  - Make various .debugfs functions return 0 unconditionally; ignore errors
  - video: Use scnprintf() to avoid buffer overflows
  - Convert drivers to simple encoders

  - drm/amdgpu: note that we can handle peer2peer DMA-buf
  - drm/amdgpu: add support for exporting VRAM using DMA-buf v3
  - drm/kirin: Revert change to register connectors
  - drm/lima: Add optional devfreq and cooling device support
  - drm/lima: Various improvements wrt. task handling
  - drm/panel: nt39016: Support multiple modes and 50Hz
