Subject: [PATCH 01/11] soundwire: intel: fix error handling on dai registration issues

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

The call to intel_register_dai() may fail because of memory allocation
issues or problems reported by the ASoC core. In all cases, when a
error is thrown the component is not registered, it's invalid to
unregister it.
