To specific, I think you did this:

  - Drop the kzalloc() failure message because those failures are logged
    elsewhere.

  - Convert other printk(KERN_DEBUG) to pci_info() or dev_err() as
    appropriate because printk(KERN_DEBUG) is ugly and don't match the
    other logging.  These could have been converted to pci_dbg() or
    dev_dbg() instead, but that would make them depend on
    CONFIG_DYNAMIC_DEBUG or DEBUG, and these messages are important enough
    that we always want them.

I think the summary (subject line) is something like:

  PCI/AER: Convert printk(KERN_DEBUG) to pci_info() or dev_err()
