UNION HWMON_PMU_EVENT_KEY(9)

💅 union hwmon_pmu_event_key(9) 🎀

okay so this is a page straight out of the Kernel API Manual, and bestie, it's about one tiny lil union that's doing main character energy in the hwmon world ✨

---

🌸 NAME 🌸

union hwmon_pmu_event_key — the key for hwmon_pmu->events, where every key represents an event, periodt 💖

And like, the union is exposed for testing so we can make sure no problems happen on big endian machines 👑 (ngl, very responsible of it).

    long type_and_num;
