Subject: Re: [PATCH v1 2/7] PCI: Convert __pci_read_base() to
 __pci_bus_read_base()

This looks weird.  Normal kernel style would be:

static inline int __pci_read_base(struct pci_dev *dev, enum pci_bar_type type,
		struct resource *res, unsigned int reg)

or

static inline int
__pci_read_base(struct pci_dev *dev, enum pci_bar_type type,

that being said, there seems to be no good agument to even make this
and inline function.

Please avoid pointless overly long lines.
