[ Upstream commit 8a8a9ac8a4972ee69d3dd3d1ae43963ae39cee18 ]
If same devices with same device IDs are present on different soundwire
buses, the probe fails due to conflicting device names and sysfs
entries:
sysfs: cannot create duplicate filename '/bus/soundwire/devices/sdw:0:0217:0204:00:0'
The link ID is 0 for both devices, so they should be differentiated by
the controller ID. Add the controller ID so, the device names and sysfs entries look
like:
sdw:1:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6ab0000.soundwire-controller/sdw-master-1-0/sdw:1:0:0217:0204:00:0
sdw:3:0:0217:0204:00:0 -> ../../../devices/platform/soc@0/6b10000.soundwire-controller/sdw-master-3-0/sdw:3:0:0217:0204:00:0
[PLB changes: use bus->controller_id instead of bus->id]
Fixes: 7c3cd189b86d ("soundwire: Add Master registration")
