Ah, ok, thanks, will fix up.

Hm, I'll look this over again and see if I can make it better.

But why are you using a "non standard" write function?  What is special
here about this?

I did use it:

$ ./scripts/get_maintainer.pl --file drivers/hid/hid-roccat-kone.c 
Jiri Kosina <jkosina@...e.cz> (maintainer:HID CORE LAYER)
linux-input@...r.kernel.org (open list:HID CORE LAYER)
linux-kernel@...r.kernel.org (open list)

You aren't listed there, perhaps a MAINTAINERS entry needs to be added?

thanks,
