Pull drm fixes from Dave Airlie:
 "I guess the main question is are things settling down, and I'd say
  kinda, these are all pretty small fixes, nothing big stands out
  really, just seems to be quite a few of them.

  Mostly amdgpu and core fixes, with some i915, tegra, vc4, panel bits.

  core:
   - Fix potential memory leak in drm_dev_init()
   - Fix potential null-ptr-deref in drm_vblank_destroy_worker()
   - Revert hiding unregistered connectors from userspace, as it breaks
     on DP-MST
   - Add workaround for DP++ dual mode adaptors that don't support i2c
     subaddressing

  i915:
   - Fix uaf with lmem_userfault_list handling

  amdgpu:
   - gang submit fixes
   - Fix a possible memory leak in ganng submit error path
   - DP tunneling fixes
   - DCN 3.1 page flip fix
   - DCN 3.2.x fixes
   - DCN 3.1.4 fixes
   - Don't expose degamma on hardware that doesn't support it
   - BACO fixes for SMU 11.x
   - BACO fixes for SMU 13.x
   - Virtual display fix for devices with no display hardware

  amdkfd:
   - Memory limit regression fix

  tegra:
   - tegra20 GART fix

  vc4:
   - Fix error handling in vc4_atomic_commit_tail()

  lima:
   - Set lima's clkname corrrectly when regulator is missing

  panel:
   - Set bpc for logictechno panels"
