Sorry I missed this patch while preparing the latest Renesas
pull request. I filter for hw/rx/ and didn't notice this
(also I was not Cc'ed in v1).

BTW to make things clear, I'm not maintaining this subsystem,
I simply try to cover for Yoshinori who is not very active.

As there are no other patch, I appreciate you taking this via
your ARM queue.
