✨ rpr0521_set_power_state(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie — like, the actual kernel docs, not a vibe. sit down, hydrate, and let's get into it 🫶

🌸 NAME 🌸

rpr0521_set_power_state — handles runtime PM state and sensors enabled status

that's it, that's the whole gig. runtime PM state + which sensors are enabled? she's doing both. multitasking icon 💅

---

🦋 SYNOPSIS 🦋

int rpr0521_set_power_state (struct rpr0521_data *data , bool on , u8 device_mask );

look at her. three args, returns an int, no cap. copy it exactly if you're writing code, okay?? character for character, bestie 🙈

---

🎀 ARGUMENTS 🎀

• data — the rpr0521 device private data. like, her personal little diary of device info 📓
• on — the state to be set for the devices in device_mask. on or off, pick a lane ✨
• device_mask — bitmask specifying for which device we need to update on state. so it's giving "which ones, specifically" energy 🔥

---

💜 DESCRIPTION 💜

okay this is the important part, so listen up fr fr 👑

Calls for this function must be balanced so that each ON should have matching OFF.

not me being dramatic but if you don't balance these, pm usage_count gets out of sync. that is a real sentence and a real consequence. no vibes-based power management allowed 😭

so: every ON gets an OFF. every OFF gets an ON. it's a two-way street, it's a situationship with rules, it's balance 🌈
