Date: Sun, 23 Nov 2014 16:00:06 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Jean-Christophe Plagniol-Villard <plagnioj@...osoft.com>, Tomi Valkeinen <tomi.valkeinen@...com>, linux-fbdev@...r.kernel.org CC: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH 1/1] video: fbdev-MMP: Deletion of an unnecessary check before the function call "mmp_unregister_path" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Sun, 23 Nov 2014 15:45:03 +0100 The mmp_unregister_path() 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.
