From 655914ab863bcc06c84270e4159fd59002d6b529 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 6 May 2013 15:54:58 +0200 Subject: [PATCH] mac80211: use just spin_lock() in ieee80211_get_tkip_p2k() ieee80211_get_tkip_p2k() may be called with interrupts disabled, so spin_unlock_bh() isn't safe and leads to warnings. Since it's always called with BHs disabled already, just use spin_lock().
