This patch could not be applied to the Debian kernel source, somehow. I
have assumed the code I should modify is this:

                if (usb_submit_urb(usbhid->urbctrl, GFP_ATOMIC)) {
                        usb_autopm_put_interface_async(usbhid->intf);
                        hid_err(hid, "usb_submit_urb(ctrl) failed\n");
                        return -1;
                }

(line 382 of drivers/hid/usbhid/hid-core.c) instead of what the patch
originally modifies.

Kernel is being compiled at the moment. Sorry for taking so long, it's
been a while since I had to do that.
