Hi Bibby,
This doesn't merge cleanly.
It seems like upstream has:
static void mtk_plane_enable(struct mtk_drm_plane *mtk_plane,
Whereas your version of "is based on some downstream version of
"drm/mediatek: Use drm_plane_helper_check_state()" which changed this
to struct drm_plane. Can you respin the set such that the
mtk_drm_plane removal patch fixes this?
Your set should apply cleanly to
https://cgit.freedesktop.org/~seanpaul/birch/?h=for-misc
Thanks,
Sean
