Subject: [PATCH v2 06/31] media: v4l: async: Drop unneeded list entry initialisation
Date: Tue, 16 May 2023 12:54:52 +0300	[thread overview]
Message-ID: <20230516095517.611711-7-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20230516095517.611711-1-sakari.ailus@linux.intel.com>

The list entry is initialised as a head in v4l2_async_register_subdev()
just before being added to the list. This isn't needed, drop the
initialisation.
