[PATCH 03/14] sony-laptop: Add support for extra keyboard events

Mattia Dongili
2009-03-26T12:58:28Z

From: Matthew Garrett <mjg59@srcf.ucam.org>

The current sony-laptop code assumes that the keyboard event method is
always located at slot 2 in the platform code. Remove this assumption and
add support for some additional hotkeys.
