devm_acpm_get_by_node(9)

💖 devm_acpm_get_by_node(9) 💖

okay so this is the devm_acpm_get_by_node(9) page from the Kernel API Manual, and it’s short, sweet, and very “managed handle” coded. bestie, let’s get into it 🫶

---

✨ NAME ✨

managed get handle using node pointer — that’s the whole name vibe, no cap 💅

---

🦋 SYNOPSIS 🦋

struct acpm_handle * devm_acpm_get_by_node (struct device *dev , struct device_node *np );

---

🎀 ARGUMENTS 🎀

• dev — device pointer requesting ACPM handle. it’s the device saying “hey bestie, can I get an ACPM handle?” 🔥
• np — ACPM device tree node. literally the ACPM node in the device tree 🌸

---

✨ RETURN ✨

on success, you get a pointer to handle. otherwise, it’s ERR_PTR(-errno). that’s the return tea, periodt 💖

---
