Subject: [PATCH AUTOSEL 5.4 022/330] drm/amd/display: Free gamma after calculating legacy transfer function
From: Nicholas Kazlauskas <nicholas.kazlauskas@....com>
[ Upstream commit 0e3a7c2ec93b15f43a2653e52e9608484391aeaf ]
[Why]
We're leaking memory by not freeing the gamma used to calculate the
transfer function for legacy gamma.
[How]
Release the gamma after we're done with it.
