So FW being broken is a social secret. But we don't care. We have tried,
nothing happens. No one moves. The crack monkeys which program it have
long moved to the next release and you hear crap like, "we don't support
linux" and other bullshit.
What we do now is to try to make the best of it - we either can handle
an error *without* firmware's help or we panic. If we can recover from
it, let's do that without screaming about something the user can't deal
with anyway.
All those FW_ERR printks cause nothing but expensive support calls, the
outcome of which is nothing. Just a lot of money down the drain.
