Subject: [PATCH 02/18] brcmsmac: use perimeter lock in add_interface() callback
Date: Wed, 2 Jan 2013 15:22:35 +0100	[thread overview]
Message-ID: <1357136572-18273-3-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1357136572-18273-1-git-send-email-arend@broadcom.com>

All callbacks that access driver functions should do that under
perimeter lock protection. The add_interface() callback was lacking
this lock.
