From ff6defa6a8fae12205d64f55db395b1fcf35af8e Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Sat, 3 Jan 2015 22:55:54 +0100 Subject: ALSA: Deletion of checks before the function call "iounmap" The iounmap() function performs also input parameter validation. Thus the test around the call is not needed. This issue was detected by using the Coccinelle software.
