Subject: [igt-dev] [PATCH i-g-t 12/17] gem_wsim: Save some lines by changing to implicit NULL checking
Date: Thu, 18 Oct 2018 16:28:10 +0100	[thread overview]
Message-ID: <20181018152815.31816-13-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20181018152815.31816-1-tvrtko.ursulin@linux.intel.com>

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

We can improve the parsing loop readability a bit more by avoiding some
line breaks caused by explicit NULL checks.
