[PATCH] wistron_btns: Generate normal key code if bluetooth or wifi card not present

[Éric Piel]

Hello Dmitry,

Here is a small patch for wistron_btns that allows laptops having
bluetooth or wifi buttons without the bluetooth/wifi hardware to report
the key press as a normal key (instead of doing nothing).

It was successfully tested by Andrew Lutomirski on his Acer C300: two
more keys working :-)

See you,
Eric

If the subsystem is not present, instead of not doing anything, report
the key press as a normal key. This is done by modifying at
initialization the copied key entry table.
