K 10 svn:author V 3 kan K 8 svn:date V 27 2009-03-23T01:13:34.709166Z K 7 svn:log V 269 Add safety check that does not allow empty strings to be queued to the devctl notification queue. Empty strings cause devctl read call to return 0 and result in devd exiting prematurely. The actual offender (ugen notes for root hubs) will be fixed by separate commit. END
