drm/amd/display: Compare clock state member to determine optimization. (e62dbcdb) · Commits · 戴 / test

[Why] It seems always request passive flip on RN due to incorrect compare clock state to determine optization. [How] Instead of calling memcmp, compare clock state member to determine the condition. Signed-off-by:
