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 Fixes: 90b86fcc47b4 ("DRM: Add KMS driver for the Ingenic JZ47xx SoCs") Signed-off-by: Paul Cercueil <paul@xxxxxxxxxxxxxxx> Reviewed-by: Sam Ravnborg <sam@xxxxxxxxxxxx> Link: https://patchwork.freedesktop.org/patch/msgid/20200716163846.174790-1-paul@xxxxxxxxxxxxxxx Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/gpu/drm/ingenic/ingenic-drm.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/gpu/drm/ingenic/ingenic-drm.c +++ b/drivers/gpu/drm/ingenic/ingenic-drm.c @@ -386,7 +386,7 @@ static void ingenic_drm_plane_atomic_upd addr = drm_fb_cma_get_gem_addr(state->fb, state, 0); width = state->src_w >> 16; height = state->src_h >> 16; - cpp = state->fb->format->cpp[plane->index]; + cpp = state->fb->format->cpp[0]; priv->dma_hwdesc->addr = addr; priv->dma_hwdesc->cmd = width * height * cpp / 4; Patches currently in stable-queue which might be from paul@xxxxxxxxxxxxxxx are queue-5.8/pinctrl-ingenic-properly-detect-gpio-direction-when-configured-for-irq.patch queue-5.8/mips-qi_lb60-fix-routing-to-audio-amplifier.patch queue-5.8/pinctrl-ingenic-enhance-support-for-irq_type_edge_both.patch queue-5.8/drm-ingenic-fix-incorrect-assumption-about-plane-index.patch
