Hi, I would like to verify this series along with the other series "PCI: dwc: fix two MSI issues" on Tegra194. I tried to apply these series on both linux-next and Lorenzo's pci/dwc branches but there seem to be non trivial conflicts. Could you please tell me which branch I can use and apply these series cleanly? FWIW, I acknowledge that the existing code does leak MSI target page every time system goes through suspend-resume sequence on Tegra194.
Thanks, Vidya Sagar
