From 24d9b755ab2b44ec56723cd8e6b578985a1f1c76 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 8 Jul 2015 21:26:02 +0200 Subject: ALSA: hda: Delete an unnecessary check before the function call "kobject_put" The kobject_put() function tests whether its argument is NULL and then returns immediately. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
