That's a good thought, but I don't think so. The dev_* macros don't
add the function name to the printed message, and we don't have a
struct device pointer in all our contexts. Even if we did, it would
be kind of forced to do that just to try to get the prefix "aoe: " and
the function name into the printks, which the new macros do nicely.
