     Input: introduce BTN/ABS bits for drums and guitars

The commit above breaks my Logitech mouse. The mouse cursor just

sits in

the middle of the screen and doesn't react to movements. dmesg is
normal, but Xorg.0.log says:

Ok, the issue is the kernel assumes ABS_MAX to be a power-of-2 minus

(used as mask). That wasn't really obvious to me. Attached is a patch
which should fix that. Could you apply it on top of linus/master and
give it a try?

Gah. I just wasted too much time bisecting down my logitech wireless
keyboard not working to within a few commits of this, and decided to
just try your patch.

And yes, it makes my keyboard work.

Dmitry, should I just apply the patch, or should we revert and use
other bits? Please, this needs to be resolved, I stopped merging when
I noticed this problem..

The patch still had problems so I'd revert it and wii bits and try again later.


Thanks.
