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

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.
