✨ thermal_of_get_trip_type(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is a lil thermal-of helper that literally just reads a trip type for you 💅 it's giving "small function, big feelings", and honestly? iconic.

---

🌸 NAME 🌸

thermal_of_get_trip_type — get the phy mode for a given device_node 🦋

yeah. that's the whole vibe. it fetches the phy mode for the device_node you hand it, no cap.

---

🌈 SYNOPSIS 🌈

int thermal_of_get_trip_type (struct device_node *np , enum
thermal_trip_type *type );

look at her. int return, two args, one of them a pointer-to-enum situation. main character signature fr fr 👑

---

🎀 ARGUMENTS 🎀

• np — pointer to the given device_node 🌱 this is the node you're snooping through, bestie
• type — pointer to the resulting trip type 🫶 this is where the answer lands when we're done

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — the function gets the trip type string from the property 'type', and then it stores its index in the trip_types table in type.

that's it. that's the whole function. she reads a property, she looks up an index, she writes it into your type pointer. lowkey elegant, highkey useful ✨

---

🔥 RETURN 🔥

• 0 on success 🎉
• or errno in the error case 😭 (so like, check it, bestie, don't just assume it slayed)
