Merge series "ASoC: codecs: rt*-sdw: memory leaks and simplifications" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

Browse Source 
While debugging unrelated memory corruption errors, I detected issues
related to the interaction with the SoundWire and ASoC cores, here are
3 small patches to fix all this.

Pierre-Louis Bossart (3):
  ASoC: codecs: rt*-sdw: don't assign slave_ops
  ASoC: codecs: rt*-sdw: fix memory leak in set_sdw_stream()
  ASoC: codecs: rt1308-sdw: remove duplicate allocation
