Subject: [PATCH 02/12] drm/amd: Remove unused variable 'value0'

Compiling AMD GPU drivers displays a warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_link_encoder.c: In function ‘dcn10_link_encoder_update_mst_stream_allocation_table’:
drivers/gpu/drm/amd/amdgpu/../display/dc/dcn10/dcn10_link_encoder.c:1222:18: warning: variable ‘value0’ set but not used [-Wunused-but-set-variable]

Get rid of it by removing the variable.
