I will confirm which license works for us.

Yes, I learned we have other tools to do the same as our driver does,
but we already have
userland using DMA through out driver. Maybe I will retire this driver

Goldfish devices are used only in Android emulator. We can pick other
numbers to avoid conflicts,
but this breaks our userland. We are ok with conflicts with drivers we
don't expect to be used.
