[PATCH v1 4/4] sparc/PCI: Use dev_printk() when possible

From: Bjorn Helgaas
Date: Mon May 21 2018 - 19:36:32 EST

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

Use the pci_info() and pci_err() wrappers for dev_printk() when possible.

Log PCI device vendor and device IDs and BAR information in the same format
used by other architectures.
