Thanks for your patch!

I sent a similar patch before:
https://lore.kernel.org/linux-renesas-soc/62adddea1fc5e9133766af2d953be7334f4622aa.1638959417.git.geert+renesas@glider.be
leading to your comment that the deeper paths should be fixed instead.

Gr{oetje,eeting}s,

                        Geert

Thanks for your help dealing with my goldfish memory :-)

I'll try to fix the deeper paths.
