In subject, s/pcie/PCIe/

Since the subject already mentions "sm8150:", maybe the "for SM8150"
is superfluous?

s/founds/found/

Rewrap to fill 75 columns.

Personally I would use INTA, INTB, etc in the comments to match the
PCI spec usage, but grep says that's a minority view.

Hi Dmitry,

Thanks for the review.
