Subject: [patch 3/8] usbtouchscreen: convert from usb_device to usb_interface
Date: Mon, 21 Dec 2009 16:22:58 -0800	[thread overview]
Message-ID: <200912220022.nBM0MwJb005038@imap1.linux-foundation.org> (raw)

From: Ondrej Zary <linux@rainbow-software.org>

Convert usbtouchscreen from storing usb_device to usb_interface. This is
needed for multi-interface touchscreen devices such as iNexio.
