HID: wacom: Delete unnecessary checks before the function call “input_free_device”
Author: Markus Elfring <elfring@users.sourceforge.net>
The input_free_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.
