[PATCH 08/19] soundwire: stream: group sdw_port and sdw_master/slave_port functions

25 Jan 2022

From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com
re-group all the helpers in one location with a code move. For
consistency the 'slave' helpers are placed before the 'master'
helpers.
Also remove unused arguments and rename the 'release' function to
'free' for consistency.
No functional change in this patch.
