✨ devm_of_led_get(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this is the page for devm_of_led_get, and honestly? it's giving "let the kernel clean up after you" and we are obsessed 🫶

---

🌸 NAME 🌸

devm_of_led_get — resource-managed request of a LED device 💡✨

---

🦋 SYNOPSIS 🦋

struct led_classdev * devm_of_led_get (struct device *dev , int index );

that's the whole vibe, no cap 🎀

---

🎀 ARGUMENTS 🎀

• dev — the LED consumer 👀 like, the device that's gonna use the LED
• index — index of the LED to obtain in the consumer 🔢 (which one you want, bestie)

---

💅 DESCRIPTION 💅

so here's the tea ☕ — the device node of the device gets parsed to find the requested LED device 🔍✨. and the LED device that comes back from this function is automatically released on driver detach 😭👑 like the kernel literally does the cleanup for you, main character energy fr fr.

it returns a pointer to a LED device, or ERR_PTR(errno) on failure 💀 — so yeah, do the vibe check on that return value, iykyk.

ngl, always check for ERR_PTR(errno) — a failure is a failure, and pretending it isn't is not the move 🙈
