Subject: [PATCH v1 5/6] iommu/dmar: Remove redundant ' != 0' when check return code
Date: Wed, 15 Feb 2017 16:42:25 +0200 [thread overview]
Message-ID: <20170215144226.34519-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20170215144226.34519-1-andriy.shevchenko-VuQAYsv1563Yd54FQh9/CA@public.gmane.org>
Usual patter when we check for return code, which might be negative
errno, is either ret or !ret.
Remove extra ' != 0' from condition.
