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. Signed-off-by: Richard Purdie <rpurdie@rpsys.net> Acked-by: Greg Kroah-Hartman <gregkh@suse.de>
