Subject: [PATCH 2/6] ath6kl: Protect ath6kl_cfg80211_vif_cleanup using rtnl_locks
Date: Thu, 14 Feb 2013 15:07:08 +0530	[thread overview]
Message-ID: <1360834628-11018-1-git-send-email-mohammed@qca.qualcomm.com> (raw)

From: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com>

ath6kl_cfg80211_vif_cleanup calls 'unregister_netdevice' which
inturn calls 'unregister_netdevice_queue' and it requires holding
rtnl_lock semaphore protection.
