Subject: [PATCH 09/11] drm/rcar-du: Annotate dma-fence critical section in commit path
Date: Thu, 21 Jan 2021 16:29:57 +0100
Message-ID: <20210121152959.1725404-10-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20210121152959.1725404-1-daniel.vetter@ffwll.ch>

Ends right after drm_atomic_helper_commit_hw_done(), absolutely
nothing fancy going on here.
