The pci_rest_bus() function calls into pci_probe_reset_slot() to determine
whether to call the slot or bus reset. The check has faulty logic in that
it does not account for pci_probe_reset_slot() being able to return an
errno. Fix by only calling the slot reset when the function returns 0.
Treat < 1 and > 1 the same.

Nit. Small typo on the first sentence (pci_rest_bus()).

Bjorn,

Are you OK to apply this series through the RDMA tree (for rc3), or do
you want to take it through PCI?

https://patchwork.kernel.org/patch/10584277/

Please don't apply the entire series yet. First patch is good to go.

Second one is a hack. We are trying to find a better solution for the second
patch.

Don't expect me to follow bugzilla too :|

I'll drop this series off patchworks then, resend when you have something..


Sure, I'm trying to contain the change to PCI tree only. Hopefully, it can go
 through Bjorn's tree. If we fail, we are back to this change. I'll ping you in
 that case.

Jason
