We cannot break user space like that, linux-firmware needs to be
backwards compatible. In other words, anything you submit to
linux-firmware needs to work with old kernels. Should this new firmware
be reverted from linux-firmware?

What about changes in the rtw89 driver? Do they still work with old
firmware?
