Subject: [PATCH 2/3] ASoC: soc-dai: add get_sdw_stream() callback
Date: Tue, 25 Feb 2020 11:00:40 -0600 [thread overview]
Message-ID: <20200225170041.23644-3-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20200225170041.23644-1-pierre-louis.bossart@linux.intel.com>
We only have a set() operation, provide the dual get() operation to
retrieve the stream information.
