Subject: [PATCH 1/2] drm/mediatek: add plane check in async_check function
Date: Thu, 13 Feb 2020 09:23:52 +0800 [thread overview]
Message-ID: <20200213012353.26815-1-bibby.hsieh@mediatek.com> (raw)
MTK do rotation checking and transferring in layer check function,
but we do not check that in atomic_check,
so add back in atomic_check function.
Fixes: 920fffcc8912 ("drm/mediatek: update cursors by using async atomic update")
