Greg -

A bit of a "philosophical" question, if I may ...

Is allowing the root user to "spam" the kernel log really a concern?
(The permissions on the attribute don't allow non-root users to write
to it.)

As a system administrator working with a sysfs API (or writing udev
rules to do so), I know that I appreciate having a meaningful message in
the log when something doesn't work.

Given that only the root user can trigger these messages, would you be
OK with dev_info()?
