Greg, here's some whitespace and long line cleanup I wanted to do last time I 
touched rom.c, but forgot.  Does it look ok to you, Jon?

Signed-off-by: Jesse Barnes <jbarnes@sgi.com>

Thanks,
Jesse

[PATCH] PCI: Clean up printks in msi.c

Add "PCI:" prefixes and fix up the formatting and grammar of printks
in drivers/pci/msi.c.  The main motivation was to fix the shouting
"MSI INIT SUCCESS" message printed when an MSI-using driver is first
started, but while we're at it we might as well tidy up all the messages.
