Subject: [PATCH 2/5] brcmfmac: Check null pointer on brcmf_dev_reset.
Date: Fri, 8 Feb 2013 12:06:32 +0100	[thread overview]
Message-ID: <1360321595-31722-3-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1360321595-31722-1-git-send-email-arend@broadcom.com>

From: Hante Meuleman <meuleman@broadcom.com>

When unloading it is possible that drvr is not null, but iflist[0]
is. So check iflist[0] pointer before using it.
