[PATCH 2/3] wistron_btns: Generic keymap

["Éric Piel" <Eric.Piel@tremplin-utc.net>]

[-- Attachment #1: Type: text/plain, Size: 385 bytes --]

This patch adds a generic map. That is, a keymap that should output the 
correct keycodes for most laptops. This is simply based on the 
observation of all those keymaps already gathered, as most of the 
wistron codes are always mapped to the same keycode.

Hopefully, this way users which have a non-supported laptop will have a 
quick and dirty way to use the multimedia keys.

wistron_btns: Generic keymap

It turns out that the mapping of the wistron code is always the same, the
main difference being some keys which may not exist and leds which might not be
present. Therefore it's possible to write a generic keymap which would allow
the use of an unknown keyboard with little drawbacks. The user can select it
specifying the parameter "keymap=generic".
