Subject: [PATCH 3/3] ASoC: soc_sdw_utils: drop bogus container_of() error handling
Date: Fri, 19 Dec 2025 15:27:15 +0100	[thread overview]
Message-ID: <20251219142715.19254-4-johan@kernel.org> (raw)
In-Reply-To: <20251219142715.19254-1-johan@kernel.org>

The dev_to_sdw_dev() helper uses container_of() to return the containing
soundwire device structure of its pointer argument and will never return
NULL.

Fixes: 4f8ef33dd44a ("ASoC: soc_sdw_utils: skip the endpoint that doesn't present")
Cc: Bard Liao <yung-chuan.liao@linux.intel.com>
