SubjectRe: [PATCH net-next 14/15] drivers/net/typhoon.c: Use (pr|netdev)_<level> macro helpers

The way the driver uses tp->name, most of the pr_<level> changes add an
extraneous "typhoon:" to the front of the messages, which is not
desirable. Your absolute change-over from PFX/ERR_PFX to pr_fmt()
KBUILD_MODNAME misses the distinction between the message where the
prefix is needed, and where it isn't.

The netdev_<level> changes are much more palatable to me than the
pr_<level> ones. I have no problem getting behind those.

I don't like these changes very much, either. I tend to work in 80 char
terminals, and the wrap of a few characters is usually annoying. I can
use a wider term, sure, but then you obscure the hint about too-deep
nesting that the more narrow terminal gives you. Also, it leaves
droppings about on those rare occasions when the code is printed 2-up.

I don't have very much to do on this driver these days, so I'll defer to
others on this issue. However, if you're going to be reformatting
things, please pull things up a line when you shorten things enough to
fit. You did it here:

But not here -- perhaps an 80 char limit, I've not looked at the patched
file:

These __func__ conversions need to go.

Pull up tp->name?

Please don't change this printk(), or change the version string, as
you'll have a redundant "typhoon:" in there now.

Pull up pci_name()? Or does that overflow 80 chars?
