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.
