✨ hwmon_device_register_with_groups(9) ✨

okay bestie, buckle up 💖 this one lives in the Kernel API Manual, section 9, and it's literally the "register w/ hwmon" girlie. she's short, she's sweet, she gets the job done 🎀

🌸 NAME 🌸

hwmon_device_register_with_groups — register w/ hwmon 💅

no cap, that's the whole name section. she said "register w/ hwmon" and meant it.

---

🦋 SYNOPSIS 🦋

struct device * hwmon_device_register_with_groups (struct device *dev ,
const char *name , void *drvdata , const struct attribute_group **groups
);

like, look at her 🫶 four whole arguments, returns a struct device *, main character energy fr fr.

---

🎀 ARGUMENTS 🎀

• dev — the parent device 👑 this is the device that's gonna be the parent of the shiny new one.
• name — the hwmon name attribute ✨ this is the name, bestie. the name attribute, specifically.
• drvdata — driver data to attach to created device 🌸 whatever driver data you've got, it gets attached to the device that gets created. simple as that.
• groups — List of attribute groups to create 💜 a list (capital L, she's fancy) of attribute groups that are gonna get created.

---

🔥 DESCRIPTION 🔥

okay so the vibe here is: you call this, it registers your hwmon device with groups, and it returns a pointer to the new device 💖 that's the good part, that's the payoff, you get a pointer back.

but listen — and I need you to actually listen 🙈 — hwmon_device_unregister must be called when the device is no longer needed. not "should", not "maybe", must. when the device isn't needed anymore, that's the cleanup call and you gotta make it. don't leave her hanging 💀
