[PATCH v6 7/9] soundwire: export sdw_compare_devid, sdw_extract_slave_id and sdw_slave_add
From: Srinivas Kandagatla <hidden>
Date: 2021-03-30 14:48:30
Also in:
alsa-devel, lkml
Subsystem:
soundwire subsystem, the rest · Maintainers:
Vinod Koul, Bard Liao, Linus Torvalds
Exporting these three functions makes sense as it can be used by other controllers like Qualcomm during auto-enumeration!
