EVIOCGBUS ioctl?

[Brad H. <bh...@bi...>]

This ioctl() is defined in <linux/input.h>, but I can't see how it is 
implemented in drivers/input/evdev.c (checked 2.4.19-pre7, and CVS). My 
sample app is returning -EINVAL to the ioctl call.

Can someone identify whether this is still to be implemented, or give me a 
pointer to where it works, and what the eight bytes (short[4]) that the bus 
address comes back in are?

If it is still to be implemented, what is is supposed to provide? If there is 
no semantics, can it be removed (or at least commented out of the header 
file?
