[PATCH] update drivers/input/keybdev.c

[Paul Mackerras]

Linus,

The following patch updates drivers/input/keybdev.c so that we can
generate either linux keycodes or ADB keycodes from keyboards that use
the input layer.  We now have ADB keyboards and mice using the input
layer as well as USB, so it is very useful to have the flexibility to
choose at runtime which type of keycodes you want to receive.  You
already have in your tree all of the other changes that we need in
order to do this, just this one file got missed somehow.

This change has been approved by the maintainer, Vojtech Pavlik.

If you decide not to take this patch, please let me know so I can
send you a patch to back out the corresponding changes that have
already been made in other files.

Paul.
