No interrupt was generated using MSI

[thesven73]

I am seeing this in my kernel log:

[   10.235625] tg3 0000:03:00.0 eth20: No interrupt was generated using MSI.
        Switching to INTx mode. Please report this failure to the PCI
        maintainer and include system chipset information

I looked through MAINTAINERS, but I can't find the PCI maintainer.
Can anyone help?

Chipset info: this happens on a Freescale i.MX6Q. Mainline 4.19 kernel.
The devicetree entry for the pcie chipset is here:

arch/arm/boot/dts/imx6qdl.dtsi:

pcie: pcie@1ffc000 {
        compatible = "fsl,imx6q-pcie", "snps,dw-pcie";
        <snip>
};
