Subject: regression 2.6.37 -> 2.6.38-rc1: after suspend backlight cannot be
	adjusted

Hi everyone,

(please Cc)

going to 2.6.38-rc1 I see the following regression: After reboot I
can easily adjust the backlight with the keys on my keyboard, but 
after a suspend-to-ram this does not work anymore.

This is a Sony laptop, and backlight is controlled by the video
acpi driver AFAIR.

Best wishes

Norbert
