__rpm_callback(9)

✨ __rpm_callback(9) ✨

okay so bestie, we're in the Kernel API Manual today and this page is literally all about one little function that makes a runtime PM callback happen for a device. it's giving "middle management of power management" and honestly? we're obsessed 🎀

---

🌸 NAME 🌸

__rpm_callback — run a given runtime PM callback for a given device. that's it, that's the whole vibe. it runs the thing. for the device. slay 💅

---

🦋 SYNOPSIS 🦋

int __rpm_callback (int (*cb)(struct device *) , struct device *dev );

look at that signature. it returns an int, it takes a function pointer and a device pointer, and no, you cannot skip the struct. periodt ✨

---

🎀 ARGUMENTS 🎀

• cb — the runtime PM callback you actually want to run. it's a function pointer of type int (*cb)(struct device *). this is the main character of the operation 🔥
• dev — the device to run the callback for. the callback gets handed this bad boy. struct device *, exactly like it says 🫶
