Re: [patch 10/14] ath9k: Use tasklet_disable_in_atomic()

Thomas Gleixner [off-list ref] writes:

From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>

All callers of ath9k_beacon_ensure_primary_slot() are preemptible /
acquire a mutex except for this callchain:

  spin_lock_bh(&sc->sc_pcu_lock);
  ath_complete_reset()
  -> ath9k_calculate_summary_state()
     -> ath9k_beacon_ensure_primary_slot()

It's unclear how that can be distangled, so use tasklet_disable_in_atomic()
for now. This allows tasklet_disable() to become sleepable once the
remaining atomic users are cleaned up.
