[PATCH v4 01/15] soundwire: renames to prepare support for master drivers/devices

Pierre-Louis Bossart
2019-12-13T05:04:29Z

Add clearer references to sdw_slave_driver for internal macros

No change for sdw_driver and module_sdw_driver to avoid compatibility
issues with existing codec devices

No functionality change.
