We recently changed ath9k to force idle on driver stop() and on resume but forgot to take into account ath9k's own virtual wiphy idle states. These are used internally by ath9k to check if the device's radio should be powered down on each idle call. Without this change its possible that the device could have been forced off but the virtual wiphy idle was left on. Cc: stable@kernel.org Cc: Paul Stewart Cc: Amod Bodas Signed-off-by: Luis R.
