Do you foresee more changes, and plan to repost, or can I fix the
interrupt numbers while applying this series?
Thank you!

Thank you for asking me about this. I intended to repost a fixed patch after PCIe patch series
was merged into PCI subsystem. Otherwise, dtbs_check will detect missing the compatible
"renesas,r8a779g0-pcie" in the dt-binding doc. But, it's under review now [1].
