There's a macro called dev_fmt (similar to pr_fmt) to do this for dev_*
printers. Also I think this would be more readable if the prefix was
"gart: " rather than "GART: ". At least from my personal experience I
get easily distracted by all-caps words in logs, because they usually
indicate something that requires immediate attention. I think it's
better to leave that up to higher level mechanisms, such as the color
keying of messages based on level by tools like dmesg.
