Subject: drm/ingenic: Fix incorrect assumption about plane->index
From: Paul Cercueil <paul@xxxxxxxxxxxxxxx>
commit ca43f274e03f91c533643299ae4984965ce03205 upstream.
plane->index is NOT the index of the color plane in a YUV frame.
Actually, a YUV frame is represented by a single drm_plane, even though
it contains three Y, U, V planes.
v2-v3: No change
Cc: stable@xxxxxxxxxxxxxxx # v5.3
