Subject: [PATCH 5/5] brcmfmac: remove unnecessary locking in trap info processing
Date: Fri, 8 Feb 2013 12:06:35 +0100	[thread overview]
Message-ID: <1360321595-31722-6-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1360321595-31722-1-git-send-email-arend@broadcom.com>

From: Piotr Haber <phaber@broadcom.com>

Locking host access in trap info processing
is not needed as bus access functions do it on
their own.
