Subject: [PATCH 2885/4131] drm/amd/display: Remove plane_res.mi check in
dce110_apply_ctx_for_surface
plane_res.mi (memory interface) can never be NULL for DCE110
Found by smatch:
drivers/gpu/drm/amd/amdgpu/../display/dc/dce110/dce110_hw_sequencer.c:2881
dce110_apply_ctx_for_surface() error: we previously assumed
'pipe_ctx->plane_res.mi' could be null (see line 2873)
