Subject: [PATCH v1 07/10] sysctl: drop away useless label
Date: Wed, 17 Feb 2016 14:17:25 +0200 [thread overview]
Message-ID: <1455711448-124103-8-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1455711448-124103-1-git-send-email-andriy.shevchenko@linux.intel.com>
We have no locking in bin_uuid(). Thus, we may remove the out label and use
return statements directly.
