Hi Jason-jh, Thank you for your patch. Please prefix this patch with 'drm/mediatek' so it is clear what the changes are.

The cursor plane should use the current plane state in atomic_async_update because it would not be the new plane state in the global atomic state since _swap_state happened when those hook are run. Fix cursor plane issue by below modification: 1. Remove plane_helper_funcs->atomic_update(plane, state) in mtk_drm_crtc_async_update. 2. Add mtk_drm_update_new_state in to mtk_plane_atomic_async_update to update the cursor plane by current plan hook and update the normal plane by the new_state. Fixes: 37418bf14c13 ("drm: Use state helper instead of the plane state pointer") Signed-off-by: jason-jh.lin <jason-jh.lin@mediatek.com> --- drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 1 - drivers/gpu/drm/mediatek/mtk_drm_plane.c | 60 ++++++++++++++---------- 2 files changed, 34 insertions(+), 27 deletions(-)
