    Subject[PATCH v2 3/7] driver core: add device_{add|remove}_group() helpers
    Date
    We have helpers that work with NULL terminated array of groups, but many
    drivers only create a single supplemental group, and do not want to declare
    a group array. Let's provide them with helpers working with a single group.
