devm_pse_alloc_pw_d(9)

💅 devm_pse_alloc_pw_d — from the Kernel API Manual, bestie ✨

Okay so real talk, this page is literally about one function and it's a whole vibe. We're in devm_pse_alloc_pw_d(9) territory — the devm_ prefix is doing its usual main-character thing, and the manual it lives in is the Kernel API Manual. Let's get into it 🎀

---

🌸 NAME 🌸

devm_pse_alloc_pw_d — allocate a new PSE power domain for a device. That's it, that's the whole job, and honestly? Iconic. ✨

---

🦋 SYNOPSIS 🦋

struct pse_power_domain * devm_pse_alloc_pw_d (struct device *dev );

Look at that signature. Clean. No cap. 💅

---

💖 ARGUMENTS 💖

• dev — the device that is registering this PSE power domain. Yeah, this is the one saying "hey, this power domain is mine, put it on my tab" 🫶

---

⭐ RETURN ⭐

You get back a pointer to the newly allocated PSE power domain. Or… error pointers 😭 so like, do the IS_ERR() check, bestie, I'm begging. 🙈

Lowkey, that's the whole page. It's a short one, and honestly it ate. 💀
