[PATCH 00/19] soundwire: stream: cleanup of 'stream' support

[Bard Liao]

This series revisits the SoundWire 'sdw_stream' support to split allocation
and configuration steps. This is necessary if for example the routines are
called multiple times from the hw_params stage. This also helps with better
error handling.

Pierre-Louis Bossart (19):
  soundwire: stream: remove unused parameter in sdw_stream_add_slave
  soundwire: stream: add slave runtime to list earlier
  soundwire: stream: simplify check on port range
  soundwire: stream: add alloc/config/free helpers for ports
  soundwire: stream: split port allocation and configuration loops
  soundwire: stream: split alloc and config in two functions
  soundwire: stream: add 'slave' prefix for port range checks
  soundwire: stream: group sdw_port and sdw_master/slave_port functions
  soundwire: stream: simplify sdw_alloc_master_rt()
  soundwire: stream: split sdw_alloc_master_rt() in alloc and config
  soundwire: stream: move sdw_alloc_slave_rt() before 'master' helpers
  soundwire: stream: split sdw_alloc_slave_rt() in alloc and config
  soundwire: stream: group sdw_stream_ functions
  soundwire: stream: rename and move master/slave_rt_free routines
  soundwire: stream: move list addition to sdw_slave_alloc_rt()
  soundwire: stream: separate alloc and config within
    sdw_stream_add_xxx()
  soundwire: stream: introduce sdw_slave_rt_find() helper
  soundwire: stream: sdw_stream_add_ functions can be called multiple
    times
  soundwire: stream: make enable/disable/deprepare idempotent
