Subject: [PATCH] ath5k: remove _bh from inner locks
Date: Fri, 15 Jun 2012 16:03:29 -0400 [thread overview]
Message-ID: <20120615200329.GA19999@localhost> (raw)
spin_unlock_bh(&txq->lock) already disables softirqs so we don't want
to do it here. Fixes smatch warnings:
drivers/net/wireless/ath/ath5k/base.c:1048 ath5k_drain_tx_buffs() error: double lock 'bottom_half:'
drivers/net/wireless/ath/ath5k/base.c:1056 ath5k_drain_tx_buffs() error: double unlock 'bottom_half:'
Reported-by: Johannes Berg <johannes.berg@intel.com>
