From a1891b9136d9b77b24d40a98785b8ded11d0fec0 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 21 Jan 2021 16:29:58 +0100 Subject: drm/tegra: Annotate dma-fence critical section in commit path Again ends just after drm_atomic_helper_commit_hw_done(), but with the twist that we need to make sure we're only annotate the custom version. And not the other clause which just calls drm_atomic_helper_commit_tail_rpm(), which is already annotated.
