Yeah. I thought about that too. I was about to send it that way, but
then I realized that we do not control the report ID from the device
(it's not overwritten by raw_event()). So it feels weird to just have
this macro in the middle of the report descriptor.
I think we can just leave it as it right now and maybe change the
whole thing later if needed.

No worries. Thanks for the reviews. Once Jiri will pull these, I'll send
the corresponding patches to DIGImend-devel for the digimend-kernel

Cheers,
