Subject: [PATCH v2 0/4] ASoC: codecs: wcd937x/8x/9x: cleanup

From: Srinivas Kandagatla <srinivas.kandagatla@....qualcomm.com>

All these 3 codecs have been duplicating two of the soundwire
functions. Noticed another new driver starting to do the same, its time
to make some helpers so that we do not duplicate these functions.

I have added two helpers of_sdw_find_device_by_node() and
sdw_slave_get_current_bank() in soundwire layer for the codecs to use them.

Changes since v1:
	- updated sdw_slave_get_current_bank do error checks on read

Srinivas Kandagatla (4):
  soundwire: bus: add of_sdw_find_device_by_node helper
  soundwire: bus: add sdw_slave_get_current_bank helper
  ASoC: codecs: wcdxxxx: use of_sdw_find_device_by_node helper
  ASoC: codecs: wcdxxxx: use sdw_slave_get_current_bank helper
