what is the log_type(WARN) stuff for?  How does that work?  You should
just use the normal dev_dbg() call and don't try to add new prefixes to
the message as that will just confuse the common parsing tools we have
for these types of things.

Also, as before, __func__ is redundant, and now you see it twice in the
output :(

thanks,
