That way the the "pvt" is flatten even more. But I think that'd make the diff even bigger without any immediate benefit. I think this module needs a bit of spring cleaning, so removing "low_ops" can be done then once the current changes settle down. > break; > > case 0x10: > - fam_type = &family_types[F10_CPUS]; > - pvt->ops = &family_types[F10_CPUS].ops;
