Subject: drm/amd/display: Fix optc2_configure warning on dcn314
From: Roman Li <roman.li@xxxxxxx>
commit e7e4f77c991c9abf90924929a9d55f90b0bb78de upstream.
[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:
<TASK>
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
