Subject: [PATCH 14/14] brcmfmac: reset suspend flag upon sdio suspend failure
Date: Tue, 25 Feb 2014 20:30:38 +0100	[thread overview]
Message-ID: <1393356639-19169-15-git-send-email-arend@broadcom.com> (raw)
In-Reply-To: <1393356639-19169-1-git-send-email-arend@broadcom.com>

The suspend callback first sets the suspend flag used in the driver
but after that the actual suspend is done, which may fail. Reset the
flag upon suspend failure.
