I think the -Dpr_fmt is especially odd and not
really acceptable as it not used anywhere else
in the kernel.

There are about 2000 cases in the kernel of the same '#define
pr_fmt...' being pasted into the top of the file, which seems a bit
cumbersome. Rather than having to paste that into each and every file
that I pr_err from,

As far as I can tell, zinc doesn't use pr_err, just
pr_info in all the selftest blocks which are only
used when DEBUG is #defined.

Perhaps all the pr_info uses should use pr_debug
instead as well as dynamic debugging which already
optionally adds KBUILD_MODINFO.

 why can't I just do this from the makefile, since
I want that same pr_fmt to copy the whole directory?

Ideally all of those

#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

uses will be removed one day soon and the default
will change.

This slightly odd use might complicate that.
