iommu: Use dev_printk() when possible
Use dev_printk() when possible so the IOMMU messages are more consistent with other messages related to the device. E.g., I think these messages related to surprise hotplug: pciehp 0000:80:10.0:pcie004: Slot(36): Link Down iommu: Removing device 0000:87:00.0 from group 12 pciehp 0000:80:10.0:pcie004: Slot(36): Card present pcieport 0000:80:10.0: Data Link Layer Link Active not set in 1000 msec would be easier to read as these (also requires some PCI changes not included here): pci 0000:80:10.0: Slot(36): Link Down pci 0000:87:00.0: Removing from iommu group 12 pci 0000:80:10.0: Slot(36): Card present pci 0000:80:10.0: Data Link Layer Link Active not set in 1000 msec Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Signed-off-by: Joerg Roedel <jroedel@suse.de>
