From 01ad444e3be719f8ad13f136a9b0d301806183c8 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Tue, 30 Mar 2021 15:47:17 +0100 Subject: [PATCH] soundwire: export sdw_compare_devid, sdw_extract_slave_id and sdw_slave_add Exporting these three functions makes sense as it can be used by other controllers like Qualcomm during auto-enumeration!
