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".
