Need a second set of eyeballs for a possible startup race condition in vc04_services/vchiq.

[Dan Carpenter]

It's hard to review this because there are no callers and the hash
you're talking about is an RPI hash...  You have no idea how lazy I am.

You're right, that code looks racy but it's almost certainly harmless
depending on how it's called.  It has to race at the very very beginning
otherwise it's fine.
