Arnaud,

The gen-snmp-subdriver.sh script is setting mib2nut[i]->oid_auto_check to NULL for new drivers (with no instructions on what to use in place of NULL). However, this seems to be only used with the "classic method" for detecting an UPS.

Is the intent to phase out the classic method, or should we just add an explicit NULL check in load_mib2nut()?
