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.

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.
