Yup, having sent the patch some git grep’ing showed me the newer driver
already has the ID for the card included.

So the problem now is .. I have both drivers enabled in kernel config:
https://github.com/LibreELEC/LibreELEC.tv/blob/master/projects/RPi/devices/RPi5/linux/linux.aarch64.conf#L2324-L2325
And This is a Linux 6.6.10 kernel boot (without this patch):
https://paste.libreelec.tv/oriented-mastodon.log
The card is visible on the USB bus but why isn’t the correct (newer)
driver probing? ¯\_(ツ)_/¯
