[PATCH 5.10 035/104] drm/amd/display: Free atomic state after drm_atomic_commit

[Greg Kroah-Hartman]

From: Victor Lu <victorchengchi...@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.
