devm_led_cla...register_ext(9)

✨ NAME ✨

okay so this is the devm_led_cla...register_ext page from the Kernel API Manual (yes the title's truncated, that's just how the kernel rolls 💅) and it's literally about devm_led_classdev_register_ext — the resource managed version of led_classdev_register_ext(). devm girlies stay winning 🫶

🌸 SYNOPSIS 🌸

int devm_led_classdev_register_ext (struct device *parent , struct
       led_classdev *led_cdev , struct led_init_data *init_data );

that's the whole vibe: returns an int, takes three pointers. periodt ✨

🎀 ARGUMENTS 🎀

• parent — the parent of the LED device 👑 like, whose kid is this LED, basically
• led_cdev — the led_classdev structure for this device 💖 this is your actual LED's whole personality
• init_data — LED class device initialization data 🌸 the setup info it gets born with

ngl bestie, if you registered it, you gotta unregister it — that's why the devm unregister is sitting right there in SEE ALSO. iconic mutual-aid behavior 💀✨

and that's the whole page!! 🍓 sign-off time: this one lives over in ./drivers/leds and it's dated October 2026 — so yeah, future-dated manual page, main character energy fr fr 👑💜 mwah, go register some LEDs 🧚‍♀️
