Thanks for the update!

Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>
i.e. will queue in renesas-devel for v5.10.

However, as no core PCI code seems to depend on CONFIG_PCI_ENDPOINT, I
would like to request the PCI endpoint people to consider making all PCI
endpoint support tristate, so we can revisit this change to the arm64
defconfig later.

Thanks!
