 "Regular fixes pull, pretty small set of fixes, a couple of i915 and
  amdgpu, one ttm, one nouveau and one omap. Probably smaller than usual
  for this time, so we'll see if something pops up next week or if this
  will continue to stay small.

  Summary:

  ttm:
   - Make ttm_bo_unpin() not wraparound on too many unpins

  omap:
   - Fix coccicheck warning in omap

  amdgpu:
   - DCN 3.0 gamma fixes
   - DCN 2.1 corrupt screen fix

  i915:
   - Workaround async flip + VT-d frame corruption on HSW/BDW
   - Fix NMI watchdog crash due to uninitialized OA buffer use on gen12+

  nouveau:
   - workaround oops with bo syncing"

[Why?]
Should only reroute gamut remap to mpc unless 3D LUT is not used and all
planes are using the same src->dest.

[How?]
Remove DCN30 specific logic for rerouting gamut remap to mpc.

[Why]
DCN30 needs to correctly program reversed gamma curve, which DCN20
already has.
Also needs to fix a bug that 252-255 values are clipped.

[How]
Apply two fixes into DCN30.

MODULE_SUPPORTED_DEVICE was added in pre-git era and never was
implemented. We can safely remove it, because the kernel has grown
to have many more reliable mechanisms to determine if device is
supported or not.

r is "u32" always >= 0,mipi_dsi_create_packet may return little than zero.
so r < 0 condition is never accessible.

WARNING: Unsigned expression compared with zero: r < 0
