Message-ID: <5469F4D5.9050908@users.sourceforge.net> Date: Mon, 17 Nov 2014 14:15:01 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Jarkko Nikula <jarkko.nikula@...mer.com>, Jaroslav Kysela <perex@...ex.cz>, Liam Girdwood <lgirdwood@...il.com>, Mark Brown <broonie@...nel.org>, Peter Ujfalusi <peter.ujfalusi@...com>, Takashi Iwai <tiwai@...e.de>, linux-omap@...r.kernel.org, alsa-devel@...a-project.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Coccinelle <cocci@...teme.lip6.fr> Subject: ASoC: omap-mcbsp: Deletion of an unnecessary check before the function call "kfree" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Mon, 17 Nov 2014 14:05:27 +0100 The kfree() 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.
