USB serial: add dynamic id support to usb-serial core
Thanks to Johannes Hölzl <johannes.hoelzl@gmx.de> for fixing a few
things and getting it all working properly.
This adds support for dynamic usb ids to the usb serial core. The file
"new_id" will show up under the usb serial driver, not the usb driver
associated with the usb-serial driver (yeah, it can be a bit confusing
at first glance...)
This patch also modifies the USB core to allow the usb-serial core to
reuse much of the dynamic id logic.
