From 1fad56424f5ad3ce4973505a357212b2e2282b3f Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Fri, 28 Jun 2013 12:24:26 +0200 Subject: [PATCH] USB: ti_usb_3410_5052: fix dynamic-id matching 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.
