Mani, could you perhaps try this series on Qcom?

I personally prefer this series over a revert because:
It allows to us to still use a PCIe endpoint that comes up after the
main system has booted, e.g. when the PCIe endpoint is a board running
pci-epf-test, without the need for a manual rescan on be bus.

If we go with revert instead, this very nice feature would be gone,
and the user would need to do a manual rescan of the bus.

One could even argue that that is a user visible regression.


Kind regards,
Niklas
