Subject: [PATCH v1 5/8] media: ov2740: Drop redundant assignments of ret = 0
Date: Tue, 26 Jul 2022 15:05:53 +0300 [thread overview]
Message-ID: <20220726120556.2881-5-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20220726120556.2881-1-andriy.shevchenko@linux.intel.com>
In some cases it might hide real bugs, in most cases here it's just
redundant as it's being reassigned immediately after initial assignment.
