Subject: [PATCH 4.19 10/50] drm/amd/display: Free atomic state after drm_atomic_commit
Date: Mon, 22 Feb 2021 13:13:01 +0100
Message-ID: <20210222121021.952826027@linuxfoundation.org> (raw)
In-Reply-To: <20210222121019.925481519@linuxfoundation.org>

From: Victor Lu <victorchengchi.lu@amd.com>

[ Upstream commit 2abaa323d744011982b20b8f3886184d56d23946 ]

[why]
drm_atomic_commit was changed so that the caller must free their
drm_atomic_state reference on successes.

[how]
Add drm_atomic_commit_put after drm_atomic_commit call in
dm_force_atomic_commit.
