Subject: [PATCH 3/4] ASoC: codecs: wcdxxxx: use of_sdw_find_device_by_node helper
From: Srinivas Kandagatla <srinivas.kandagatla@....qualcomm.com>
use of_sdw_find_device_by_node helper function, rather than duplicating
this function in every codec driver.
Signed-off-by: Srinivas Kandagatla <srinivas.kandagatla@....qualcomm.com>
