The code above generates the file hid-dummy.h based on
the HID_COMPAT_LOAD_DRIVER(*) text in a few .c files.
So what I try to say is that we should replace the above with
a hid-dummy.h file that is handedited.
We could stick a few comments in the .h file explaining the usage too.
Or maybe I'm just confused and misunderstood what the code does?
