I just looked at the tree; it still has locking issues, and needs
further review. You must protect the list from modification while you
iterate it looking for an match on the requested firmware. Also, was it
legal to call release_firmware() from an atomic context? It can now
sleep, which may be an issue...

Also, should any two drivers share the same firmware,
release_firmware_all() could leave one of them without its firmware, but
I'm not sure if that is an issue either.

Please drop that patch from the series for now; I'm not happy with it,
as it reintroduces things I've asked be changed. If you get the core
firmware_class issues fixed up, I'll respin what I had.
