This prevents the output of just
dummy:
in the boot log.

Hello,
probably this really only applies to the dummy regulator. If not it
might be more sensible to do:
if (!buf[0])
buf = "no parameters";
or similar. Other than that I wonder if setting the devicename from
"dummy" to say "regulator-dummy" would be an improvement, too.
Best regards
Uwe
