Subject: [PATCH v2 0/2] PCI: dwc: Add support for 64-bit MSI target addresses

Hi All,

I have updated the patch series based on the build error reported by the
kernel test robot which found an issues with the new inline function when
PCIE_DW_HOST isn't set. Additionally, I have updated the DMA alloc error
handling for the first patch which was reported to me directly by Isaac
Manjarres. Basically, we don't need to check for a DMA mapping error since
dma_alloc_coherent() will free the memory when a mapping error occurs.

Please take a look and let me know if you have any questions or concerns.

Thanks,
Will
