[PATCH 07/14] sony-laptop: VGN-A317M hotkey support

[Mattia Dongili <malattia@linux.it>]

From: Harald Jenny <harald@a-little-linux-box.at>

This laptop has 5 SPIC managed buttons above the keyboard:
sound + and - as well as brightness, zoom and S1.
Possibly the entire VGN-A serie behaves the same.
