The licensing seems a little more complicated than that

Per the QEMU LICENSE file new contributions must be  GPL v2-or-later

This is v2-only.

If this v2-only license is inherited due to the file being derived
from another pre-existing file in QEMU that was v2-only, we could
possibly make an exception to allow another v2-only file in tree.
Preferably it should be v2-or-later though.

A BSD license variant. OK since its GPL compatible and just a header file
copied from a 3rd party project.

This is  v2-or-v3-only, which is not OK for QEMU.

It needs to be v2-or-later

Again  v2-or-v3-only.

There's many more files with this same problem but I'll stop pointing
them out now.

If this is to be included in QEMU,  Veertu & Google (and any other
copyright holders) would have to agree to change these files to
v2-or-later

Daniel
