Subject: [PATCH v2 2/5] usb: musb: call musb_port_suspend from musb_bus_suspend
Date: Tue, 1 Oct 2013 15:39:54 +0200 [thread overview]
Message-ID: <1380634797-29541-3-git-send-email-zonque@gmail.com> (raw)
In-Reply-To: <1380634797-29541-1-git-send-email-zonque-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
Make musb_port_suspend() externally available, and call it when to host
goes into suspend. This allows the core to go into suspend while a
device is connected.
