That's good enough as far as I'm concerned.

Yes, "Zbit Semiconductor Inc" moved from bank 9 to bank 10 (and lost
its dot) somewhere between JEP106AQ and JEP106AX. That's confusing but
the patch is correct.

I don't know either ;-) I don't think it really matters to be honest,
so we can just take what the JEDEC specification has.

I'm more worried by the fact that some names are not listed in the same
order in the patch as in the specification. For bank 9, names 104-109
("Boya ..." to "Guangzhou Si Nuo ...") appear in the patch after
"Starsway Technology Limited" which is supposed to be number 126 (and
in a different order too). Vincent, can you please double check?

The rest of the list looks good.
