led_classdev_register(9)

💖 NAME 💖

okay so this is led_classdev_register(9) from the Kernel API Manual, and the whole name-card moment is: led_classdev_register — register a new object of LED class. no cap, that's the function. ✨

🛠️ SYNOPSIS 🛠️

int led_classdev_register (struct device *parent , struct led_classdev
*led_cdev );

bestie, that's the exact signature — don't come for me about the line break. 💅

🎀 ARGUMENTS 🎀

• parent — the LED controller device this LED is driven by. like, the device that's driving this LED.
• led_cdev — the led_classdev structure for this device. that's your LED's little paperwork. 🗂️

🌸 DESCRIPTION 🌸

Register a new object of LED class, with the name derived from the name property of the passed led_cdev argument. so you pass in led_cdev, and the name comes from its name property. that's the tea. 🫖✨

🔥 RETURN 🔥

0 on success, or a negative error value on failure. when it's 0 we're slaying; when it's negative, it's giving error and we cry 😭💔.
