Subject: [PATCH 1/4] usb: rename USB devices to reflect bus structure
Date: Thu, 20 Jun 2013 16:05:22 +0200	[thread overview]
Message-ID: <1371737125-18820-2-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1371737125-18820-1-git-send-email-s.hauer@pengutronix.de>

This renames the USB devices to reflect the bus structure.
The base name for a USB device is usb<devno>. For each child
device we add a -<parent-port-no>. This makes it more easy
to identify devices.
