Subject: Re: [PATCH v2] PCI: rockchip: Use 64-bit mask on MSI 64-bit PCI address

Hello,
> A 32-bit mask was used on the 64-bit PCI address used for mapping MSIs.
> This would result in the upper 32 bits being unintentionally zeroed and
> MSIs getting mapped to incorrect PCI addresses if the address had any

> Replace 32-bit mask by appropriate 64-bit mask.
Applied to controller/rockchip, thank you!
