commit 61ffcafafb3d985e1ab8463be0187b421614775c
Author: Karsten Keil <kkeil@suse.de>
Date:   Sat Sep 17 23:52:42 2005 +0200

    [PATCH] Fix ST 5481 USB driver

    The old driver was not fully adapted to new USB ABI and does not
    work.

+	in->urb[0]->transfer_flags |= URB_ASYNC_UNLINK;
 	usb_unlink_urb(in->urb[0]);
+	in->urb[1]->transfer_flags |= URB_ASYNC_UNLINK;
 	usb_unlink_urb(in->urb[1]);
