[PATCH v1 0/7] iommu: Minor cleanups and dev_printk() usage

[Bjorn Helgaas]

I've had these minor iommu cleanups lying around for a while, but the ugly
dmesg logs from [1] prompted me to finally post them.  Take what you like,
ignore the rest, and tell me so I can clear out my queue of old stuff.

These fix no actual bugs.
