Compiling AMD GPU drivers displays a warning:

drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_capability.c: In function ‘dpcd_set_source_specific_data’:
drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_dp_capability.c:1290:32: warning: variable ‘result_write_min_hblank’ set but not used [-Wunused-but-set-variable]

Get rid of it by removing the variable 'result_write_min_hblank' and 'hblank_size'.
