Thanks for the patch!

In my opinion your idea is good but only qcom driver is able to detect failure
in the specific host init routine, all others have a 'return 0' even if
something not well init. I would recomend that we take this issue a bit further
and add the error checking to all specific pci drivers in order to make them as
robust as qcom'.

Thanks,
