[PATCH 03/10] staging: fsl-mc: simplify couple of deallocations

From: laurentiu.tudor
Date: Wed May 31 2017 - 06:59:34 EST


From: Laurentiu Tudor <laurentiu.tudor@xxxxxxx>

Simplify a couple of deallocations code paths. This also
fixes these checkpatch.pl false positives:
"WARNING: kfree(NULL) is safe and this check is
probably not required"
