CVE-2022-49773

CVE-2022-49773 affects the Linux kernel (drm/amd/display for DCN314). Root cause: optc2_configure_crc() wraps optc1_configure_crc() plus extra registers not applicable to dcN314, which can trigger a warning trace. Mitigation/Fix: use optc1_configure_crc() directly. References note patches in kern...
