Subject: [PATCH 17/19] soundwire: stream: introduce sdw_slave_rt_find() helper
Date: Wed, 26 Jan 2022 09:17:13 +0800 [thread overview]
Message-ID: <20220126011715.28204-18-yung-chuan.liao@linux.intel.com> (raw)
In-Reply-To: <20220126011715.28204-1-yung-chuan.liao@linux.intel.com>
From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
Before we split the alloc and config steps, we need a helper to find
the Slave runtime for a stream. The helper is based on the search loop
in sdw_slave_rt_free(), which can now be simplified.
