Date: Thu, 20 Nov 2014 11:20:29 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Mauro Carvalho Chehab <m.chehab@...sung.com>, linux-media@...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] [media] i2c: Deletion of an unnecessary check before the function call "rc_unregister_device" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Thu, 20 Nov 2014 11:13:16 +0100 The rc_unregister_device() 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.
