Oooh, yes you are right. This was a leftover when we started porting Ranchu as a legacy platform.
We will fix it in V8. Thank you.
Kind regards,

Why? Why do you need to set the struct of_device_id data field? The generic
code only provides the match data to the machine fixup_fdt callback which you
don't implement, so the value is never used.
