[PATCH] i2c-HID: Delete unnecessary checks before the function call "gpiod_put"

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.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.
