3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <jhovold@gmail.com>
commit 1fad56424f5ad3ce4973505a357212b2e2282b3f upstream.
The driver failed to take the dynamic ids into account when determining the device type and therefore all devices were detected as 2-port devices when using the dynamic-id interface.
Match on the usb-serial-driver field instead of doing redundant id-table searches.
