Subject: [PATCH v2 04/12] media: ccs: Correct error handling in ccs_register_subdev
Date: Mon, 18 Sep 2023 15:51:30 +0300	[thread overview]
Message-ID: <20230918125138.90002-5-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20230918125138.90002-1-sakari.ailus@linux.intel.com>

ccs_register_subdev() did not clean up the media entity in error case, do
that now. Also switch to goto based error handling.
