Date: Wed, 8 Jul 2015 22:30:44 +0200 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: Jiri Kosina <jkosina@...e.cz>, linux-input@...r.kernel.org Cc: Linux Kernel Mailing List <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> Subject: [PATCH] i2c-HID: Delete unnecessary checks before the function call "gpiod_put" From: Markus Elfring <elfring@...rs.sourceforge.net> Date: Wed, 8 Jul 2015 22:12:25 +0200 The gpiod_put() function performs also input parameter validation by forwarding its single input pointer to the gpiod_free() function. Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software.
