[PATCH] Drop ProGear backlight driver

From: Marcin Juszkiewicz
Date: Mon Aug 27 2012 - 11:01:40 EST

From: Marcin Juszkiewicz <marcin.juszkiewicz@xxxxxxxxxx>

This driver was for ProGear webpad device which was produced in
2000/2001 and is not available on a market. I no longer have this
hardware so can not even check how Linux works on it.
