mwl8k: disable softirqs when accessing sta_notify_list
Use spin_[un]lock_bh in mwl8k_sta_notify(). The sta_notify handler is required to be atomic, yet it can be called in process context, so make sure one call won't preempt another. Signed-off-by: Pavel Roskin <proski@gnu.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>
