This "driver" was supposed to implement the handle-hw-errors-in-fw glue
crap. The thing is, no one has been using it properly because there's
not even a single firmware vendor who has managed to produce a working
fw glue reporting errors properly. At least I haven't seen one.

Which means, no one is really using this. And now ARM start using it for
real and shit hits fan.

And I'd love to fix it but finding a box which *actually* has a usable
GHES glue is, as I mentioned above, almost impossible so testing fixes
would be hard. I need to figure out something...
