Subject: [ 51/62] dell-laptop: touchpad LED should persist its status after S3

3.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: AceLan Kao <acelan.kao@...onical.com>

commit 2d5de9e84928e35b4d9b46b4d8d5dcaac1cff1fa upstream.

Touchpad LED will not turn on after S3, it will make the touchpad status
doesn't consist with the LED.
By adding one flag to let the LED device restore it's status.
