Hi,

I finally was able to spend some time looking over Samuel's patch set
switching input LEDs from custom implementation over to standard LED 
class
devices and I think this is the shape I am reasonably happy with. The
changes:

2. There are no per-input device triggers. Input devices only carry 
LEDs
and those LEDs use one of the system-wide triggers. Which ones is to 
user
to decide. The default triggers are the one defines by keyboard 
handler for
it's standard LED states.

Please take a look and see if you see any holes.

What would the quirk for a keyboard not having LEDs look like?

In GNOME, we want to pop up a on-screen display when pressing, say, the
Caps Lock key on a keyboard that doesn't have any such keys (such as my
Lenovo X1 Carbon and the Logitech K750 that's plugged into it in my
case).

Cheers
