Ah, I didn't realize that you want it to be used by some acutal userspace
applications. Out of curiosity -- what is the usage pattern you are
targetting?

The idea behind debugfs-provided userspace descriptor is that driver
developer is easily able to inspect the descriptor, and write a kernel
driver that fixes it up in case it is bogus.
There were also efforts to make the report descriptor replaceable in a
request_firmware() way, but that never converged to state in which it
could be applied IIRC.
