From 65f704a52ec5db356c58f8ba53a31d3aef02737f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 13 Feb 2013 17:39:53 +0100 Subject: mac80211: use spin_lock_bh() for tim_lock There's no need to use _irqsave() as the lock is never used in interrupt context. This also fixes a problem in the iwlwifi MVM driver that calls spin_unlock_bh() within its set_tim() callback.
