commit 61ffcafafb3d985e1ab8463be0187b421614775c
Author: Karsten Keil <kkeil@xxxxxxx>

[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]);
