Subject: [PATCH v2 2/7] ASoC/soundwire: intel: simplify callbacks for params/hw_free
From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>
We don't really need to pass a substream to the callback, we only need
the direction. No functionality change, only simplification to enable
improve suspend with paused streams.
