Hi,
here comes a series of small diffs which add generic support for
keyboard backlights.
Please find below the first diff, which adds new ioctls to wskbd(4) to
control keyboard backlights.
In contrast to an earlier diff from jcs, I have chosen to use a struct
in favor of a simple (unsigned) int as depending on the vendor
(Thinkpad, Apple, ...) different min/max values for the brightness of
the keyboard backlight are possible.
Comments, OK?
Thanks,
Regards,
Joerg
