True story. Strange name that.

If you have all those patches ready, you could do a first patch adding
the PCI ID to pci_ids.h only.

Then follow with the different driver changes, i.e. sdhci-pci.c,
i2cpiix4, and so on and make it clear in the 0/n message that they all
depend on the first one.

Or something along those lines.

Thanks.
