[PATCH 2/4] PCI: pciehp: Replace ctrl_*() with pci_*()

From: fred
Date: Sat Apr 27 2019 - 15:13:25 EST

From: Frederick Lawler <fred@xxxxxxxxxxxx>

Hotplug useses custom ctrl_*() dev_*() printk wrappers for logging
messages. To make hotplug conform to pci logging, replace uses of these
wrappers with pci_*() printk wrappers. In addition, replace any
printk() calls with pr_*() wrappers.
