Message-ID: <54567788.9060008@users.sourceforge.net> Date: Sun, 02 Nov 2014 19:27:20 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Jaroslav Kysela <perex@...ex.cz>, Takashi Iwai <tiwai@...e.de>, alsa-devel@...a-project.org CC: linux-kernel@...r.kernel.org, kernel-janitors@...r.kernel.org, trivial@...nel.org, Coccinelle <cocci@...teme.lip6.fr> Subject: [PATCH 1/1] PCI: EMU10K1: Deletion of unnecessary checks before three function calls The functions kfree(), release_firmware() and snd_util_memhdr_free() 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.
