Subject: Re: [PATCH 1/2] bluetooth: Use more current logging styles

Hi Joe,

That is all fine, but why not just change BT_INFO to point to bt_info
and BT_ERR to bt_err first instead of having this huge patch mixed in
with the changes. The size measurement should be no different.

> Add newlines to uses of bt_info and bt_err.

Why is this a good thing?

And in your patch we have bt_err not having \n\n in the end.

Again, I am not a huge fan to squeeze this all in one patch.

Size numbers look good. So I am all for this, but not just in one big
patch.
