6.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Himal Prasad Ghimiray <himal.prasad.ghimiray@xxxxxxxxx>
[ Upstream commit f38c4d224aa37fce1e3fe05db4377ef888f0737f ]
The drmm_add_action_or_reset function automatically invokes the
action (free_gsc_pkt) in the event of a failure; therefore, there's no
necessity to call it within the return check.
-v2
