Subject[PATCH 06/12] gpu/drm: Ingenic: Fix incorrect assumption about plane->index
Date
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.

Cc: stable@vger.kernel.org # v5.3
Fixes: 90b86fcc47b4 ("DRM: Add KMS driver for the Ingenic JZ47xx SoCs")
Signed-off-by: Paul Cercueil <paul@crapouillou.net>
