From: Markus Elfring Date: Sat, 3 Jan 2015 21:55:54 +0000 (+0100) Subject: ALSA: Deletion of checks before the function call "iounmap" X-Git-Tag: fixes-v4.0-rc1~146^2~69 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff6defa6a8fae12205d64f55db395b1fcf35af8e;p=pandora-kernel.git 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.
