2020-02-19drm/amd/display: Don't take the address of skip_scdc_overwrite in ↵Nathan Chancellor1-2/+1
dc_link_detect_helper Clang warns: ../drivers/gpu/drm/amd/amdgpu/../display/dc/core/dc_link.c:980:36: warning: address of 'sink->edid_caps.panel_patch.skip_scdc_overwrite' will always evaluate to 'true' [-Wpointer-bool-conversion] if (&sink->edid_caps.panel_patch.skip_scdc_overwrite) ~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~ 1 warning generated. This is probably not what was intended so remove the address of operator, which matches how skip_scdc_overwrite is handled in the rest of the driver. While we're here, drop an extra newline after this if block.
