[PATCH] rt2x00: Stop link tuning when radio is down
As pointed out by Modestas Vainius the link tuner could continue working while the radio is already down. This because at the start of disable_radio the ENABLED_RADIO flag is cleared and causes the toggle_rx to skip the stop_link_tuner() call. This will add a check to the start of the link tuner which will automatically stop the link tuner when the radio is disabled. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
