[media] redrat3: errors on unplug
In an usb disconnect handler, the urbs have already been cancelled so the attempt to disable the IR receiver just results in errors: [ 899.638862] redrat3 7-2:1.0: redrat3_send_cmd: Error sending rr3 cmd res -110, data 0 [ 899.638870] redrat3 7-2:1.0: redrat3_disable_detector: detector status: 251, should be 0 Signed-off-by: Sean Young <sean@mess.org> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
