From: Markus Elfring Date: Thu, 5 Feb 2015 20:40:29 +0000 (+0100) Subject: uwb/whci: Delete an unnecessary check before the function call "umc_device_unregister" X-Git-Tag: v4.1-rc1~154^2~71 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b29582b15ff4049de5780e27a28ed7b3ded3f969;p=profile%2Fcommon%2Fplatform%2Fkernel%2Flinux-artik7.git uwb/whci: Delete an unnecessary check before the function call "umc_device_unregister" The umc_device_unregister() 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.
