Merge series "ASoC: dapm/pins: handle component prefix" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:
SoundWire machine drivers make a heavy use of component prefixes to uniquify control names. This however results in errors when looking for widgets or pins. This patchset suggests two solutions but feedback or suggestions on how to take the prefix into account would be welcome.
