[PATCH] drm/amd/display: kernel-doc: document mpc_color_caps.num_rmcm_3dluts

Posted by Akiyoshi Kurita 1 week, 5 days ago

Add the missing @num_rmcm_3dluts field description to silence a
kernel-doc warning. While here, fix a typo in the same block
("pre-definied" -> "pre-defined") and clarify the oGAM description.

No functional change.
