Subject: [PATCH 6/9] usb: gadget: r8a66597: use generic map/unmap routines
Date: Tue, 24 Jan 2012 13:45:27 +0200	[thread overview]
Message-ID: <1327405543-27589-7-git-send-email-balbi@ti.com> (raw)
In-Reply-To: <1327405543-27589-1-git-send-email-balbi@ti.com>

those routines have everything we need to map/unmap
USB requests and it's better to use them.
