From: Markus Elfring Date: Thu, 9 Jul 2015 06:08:15 +0000 (+0200) Subject: HID: wacom: Delete unnecessary checks before the function call "input_free_device" X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=67e123ff0e9a71fcf19f83827d59f73076f5bd1a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git HID: wacom: Delete unnecessary checks before the function call "input_free_device" 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.
