## Overview

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:
<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

## Affected

- `Linux >= 2ce0b2186c057a54a4d980b296bd1659d0091716 < f67ef5aa88e3db0a13ae3befab2ddf14ac00a91c`
- `Linux >= 2ce0b2186c057a54a4d980b296bd1659d0091716 < e7e4f77c991c9abf90924929a9d55f90b0bb78de`
