I think all these mdev core changes belong into a separate commit with a
separate commit log.

Weird indentation. But I think it would be best to just kill off the
mdev_init wrapper anyway.

Same here.

Btw, I think we don't even need ->match with the switch to use
device_bind_driver that I suggested.

Err, no. vfio should remain EXPORT_SYMBOL_GPL, just because the weird
mdev "GPL condom" that should never have been merged in that form went away.
