Clearly, mainline works differently. Ideally you do want to get the
firmware in linux-firmware.git. The kernel and firmware are then more
likely to by upgraded at the same time. However, you should not assume
so. Maybe in mainline you can then support the last 4 firmware
versions, and issue an error if a version older than that is found.

However, until the firmware is easily available via linux-firmware,
you probably should be backwards compatible for a longer period.
