Just found a previous bug report, so we can add here:

Closes: https://lore.kernel.org/all/CA+G9fYu7Ug0K8h9QJT0WbtWh_LL9Juc+VC0WMU_Z_vSSPDNymg@mail.gmail.com/

since reg->type is an enum and we are handling all the values, another
possible approach is to remove the default handling and then the
compiler will warn you of missing cases if built with -Wswitch.

Any of the approaches seem good to me.
