Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix optc2_configure warning on dcn314

[Why] dcn314 uses optc2_configure_crc() that wraps optc1_configure_crc() + set additional registers not applicable to dcn314. It's not critical but when used leads to warning like: WARNING: drivers/gpu/drm/amd/amdgpu/../display/dc/dc_helper.c Call Trace: generic_reg_set_ex+0x6d/0xe0 [amdgpu] optc2_configure_crc+0x60/0x80 [amdgpu] dc_stream_configure_crc+0x129/0x150 [amdgpu] amdgpu_dm_crtc_configure_crc_source+0x5d/0xe0 [amdgpu]

[How] Use optc1_configure_crc() directly
