[PATCH 07/12] drm/amd/display: Remove unused variable 'optc'

[Caio Novais]

Compiling AMD GPU drivers displays a warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_hwseq.c: In function 
???dcn30_enable_writeback???:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn30/dcn30_hwseq.c:326:34: warning: 
variable ???optc??? set but not used [-Wunused-but-set-variable]

Get rid of it by removing the variable.
