From 655bfd7aebb12481ab9275284d9500bee5ba3e70 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 9 Jul 2007 12:17:24 +0100 Subject: backlight: Convert from struct class_device to struct device Convert the backlight and LCD classes from struct class_device to struct device since class_device is scheduled for removal. One nasty API break is the backlight power attribute has had to be renamed to bl_power and the LCD power attribute has had to be renamed to lcd_power since the original names clash with the core. I can't see a way around this.
