Linux uses the dev_name() when identifying each of these controllers in
/sys/class/UDC, as such changing the name here will break existing USB
ConfigFS Gadget users.

We had this fixed for a while, but where forced to revert it.


So I think, in order for us to merge this without breaking AOSP, we'd
need to come up with a way to retain the old UDC name (perhaps a label
property?)

Regards,
Bjorn
