Unfortunately I don't think that's a "guess" that some distributors such
as Fedora can risk to take. Although ALSA is of course part of a "Linux
... kernel", the wording "as part of" is ambiguous and there's certainly
an argument that a standalone ALSA firmware package (i.e. not
distributed along with the rest of the kernel) is not "distribution...as
part of" a kernel.
Much though I'd *like* these firmwares to be distributable, unless those
licensing terms get changed, I think we'll have to drop those particular
firmwares in Fedora.

That's useful, thanks. Is the plan to drop the in-kernel ones at some
point then? At least this means if we do drop the firmware it won't have
any negative effect, at least at the moment.
