Hi Bjorn,

So this is how the diff looks like over this patch:

                dev_err(pp->dev, "link already up\n");



And the subject looks like this now:
PCI: spear: Add PCIe driver for ST Microelectronics SPEAr13xx

I may skip sending a V10 for this and directly send a pull request as
there aren't any significant changes suggested in V9.

Thanks.

Patch
