From 10a9990c10447a7bfe9dc016629898814741d090 Mon Sep 17 00:00:00 2001 From: Frederick Lawler Date: Tue, 7 May 2019 18:24:47 -0500 Subject: PCI/DPC: Log messages with pci_dev, not pcie_device Log messages with pci_dev, not pcie_device. Factor out common message prefixes with dev_fmt(). Example output change: - dpc 0000:00:01.1:pcie008: DPC error containment capabilities... + pcieport 0000:00:01.1: DPC: error containment capabilities...
