From: Markus Elfring <redacted> 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.
