      drm/amd/powerplay: overwrite ODSettingsMin for UCLK_FMAX feature · 3a301bc5
      Evan Quan authored 
      For UCLK_FMAX OD feature, SMU overwrites the highest UCLK DPM level freq.
Therefore it can only take values that are greater than the second highest
DPM level freq.

      drm/amd/display: Fix reference counting for struct dc_sink. · dcd5fb82
      Mathias Fröhlich authored 
      Reference counting in amdgpu_dm_connector for amdgpu_dm_connector::dc_sink
and amdgpu_dm_connector::dc_em_sink as well as in dc_link::local_sink seems
to be out of shape. Thus make reference counting consistent for these
members and just plain increment the reference count when the variable
gets assigned and decrement when the pointer is set to zero or replaced.
Also simplify reference counting in selected function sopes to be sure the
reference is released in any case. In some cases add NULL pointer check
before dereferencing.
At a hand full of places a comment is placed to stat that the reference
increment happened already somewhere else.

This actually fixes the following kernel bug on my system when enabling
display core in amdgpu. There are some more similar bug reports around,
so it probably helps at more places.

This patch is based on agd5f/drm-next-5.1-wip. This patch does not require
all of that, but agd5f/drm-next-5.1-wip contains at least one more dc_sink
counting fix that I could spot.

      drm/amdgpu/powerplay: add missing breaks in polaris10_smumgr · 6feaa419
      Alex Deucher authored 
      This was noticed by Gustavo and his -Wimplicit-fallthrough
patches.  However, in this case, I believe we should have breaks
rather than falling though, that said, in practice we should
never fall through in the first place so there should be no
change in behavior.
