I found this series with the address system suspend support

[1] https://lore.kernel.org/linux-pci/20251029-rockchip-pcie-system-suspend-v4-0-ce2e1b0692d2@collabora.com/

This patch will conflict with
[2] https://lore.kernel.org/linux-pci/20251029-rockchip-pcie-system-suspend-v4-3-ce2e1b0692d2@collabora.com/

So please drop my patch.

Thanks
-Anand
