 I think that it also makes sense to either remove indirect matching or make
 admtemp more resistant to false matches.  This would also cover other cases.
 For example, dbcool.c already has such a check by calling dbcool_chip_ident()
 from dbcool_match().  I think that we could add a similar function called
 from admtemp_match() and also do the same for adm1026, where we already have
 adm1026_ident() but don't call it from adm1026_match().
