Subject: [PATCH 09/16] brcmfmac: remove use of unconditional access of struct wireless_dev::netdev
Date: Fri, 5 Apr 2013 10:57:47 +0200	[thread overview]
Message-ID: <1365152274-4252-10-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1365152274-4252-1-git-send-email-arend@broadcom.com>

With the introduction of the P2P_DEVICE interface type an instance of
struct wireless_dev does not always have a netdev assigned to it. Better
use container_of() construct to obtain internal structure and go from
there.
