    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")
