Darren Salt 7695fb04ac eeepc-laptop: fix oops when changing backlight brightness during eeepc-laptop init 
I got the following oops while changing the backlight brightness during
startup.  When it happens, it prevents use of the hotkeys, Fn-Fx, and the
lid button.

It's a clear use-before-init, as I verified by testing with an
appropriately-placed "else printk".
