device_pm_sleep_init(9)

💖 device_pm_sleep_init — bestie's guide to the Kernel API Manual 💖

okay so real talk, we're in the Kernel API Manual today, and the star of the show is device_pm_sleep_init. it's one of those tiny-but-load-bearing functions that the power management girlies could not function without. let's get into it ✨

---

🌸 NAME 🌸

device_pm_sleep_init — initializes the system suspend-related device fields. that's the whole job. she's a setup girlie, and she does it well 🎀

---

✨ SYNOPSIS ✨

void device_pm_sleep_init(struct device *dev);

literally one call. no tricks, no secret extra params, no cap 🫶

---

🦋 ARGUMENTS 🦋

• dev — the device object being initialized. that's it, that's the whole input. hand her a struct device * and she handles the rest 💅

like I said. entire friend group. iconic behaviour honestly 🌈

ngl, the original page doesn't list any return value, errors, or flags for this one — it's a void function with a single argument and a single purpose. don't go looking for drama that isn't there, bestie 🙈
