They can't grant that permission. Every single person who had contributed
to the Linux kernel would have to agree. The GPL prohibits including
software that isn't itself GPL'd from being combined with GPL'd software.
The issue is not permission to distribute this driver, the issue is
permission to distribute the *kernel*. The kernel's license prohibits
distrubiting it in combination with works that have licenses more
restrictive than the GPL.

That's more restrictive than the GPL. So if you link this with a GPL'd
work, the entirety must be distributed under the GPL, which you can't do
since you can't authorize the unrestricted use of the firmware

Bingo.

He didn't say this made the firmware unredistributable, he said it made the
*kernel* unredistributable. Since you can't GPL the firmware, the kernel as
a whole is not GPL. You cannot distribute a non-GPL Linux kernel because the
GPL prohibits it as the GPL applies to everything else in the kernel.

You *definitely* are wrong. The entirety of the GPL would be negated if you
were correct.
