From: Felix Kuehling <Felix.Kuehling@xxxxxxx>
commit 66f7903779fbbc620bf1040017e4833ef6a0b541 upstream.
mutex_unlock before the exit label because all the error code paths that
jump there didn't take that lock. This fixes unbalanced locking errors
in case of restore errors.
Fixes: 40e8a766a761 ("drm/amdkfd: CRIU checkpoint and restore events")
