From f0acd28c87ad2a5d1b40403fdd5defda2961b2a1 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 17 Nov 2014 10:44:33 +0100 Subject: [PATCH] ALSA: hda: Deletion of unnecessary checks before two function calls The functions kfree() and release_firmware() test whether their argument is NULL and then return immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
