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 bus ID. Add the bus ID so, the device names and sysfs entries look like:
I am pretty sure this will break Intel platforms by changing the device names.
sof_sdw.c: else if (is_unique_device(adr_link, sdw_version, mfg_id, part_id, sof_sdw.c: "sdw:%01x:%04x:%04x:%02x", link_id, sof_sdw.c: "sdw:%01x:%04x:%04x:%02x:%01x", link_id,
device id name changes shouldn't break things, what is requring them to look a specific way?
