'bk pull http://linux-input.bkbits.net:8080/linux-input' should also
work.
===================================================================
ChangeSet@1.448, 2002-07-25 16:36:05+02:00, vojtech@twilight.ucw.cz
Add EVIOCSABS() ioctl to change the abs* informative
values on input devices. This is something the X peoople
really wanted.
Rename input_devinfo to input_id, it's shorter and more
to the point.
Remove superfluous printks in uinput.c
Clean up return values in evdev.c ioctl.
