led_compose_name(9)

🌸 led_compose_name 🌸

okay bestie, this is the Kernel API Manual page for led_compose_name (section 9) 💅. It’s giving “compose an LED class device name” and we’re obsessed ✨.

🎀 NAME 🎀

led_compose_name — compose LED class device name 🦋

✨ SYNOPSIS ✨

       int led_compose_name (struct device *dev , struct led_init_data
       *init_data , char *led_classdev_name );

💖 ARGUMENTS 💖

• dev — LED controller device object 🔥
• init_data — the LED class device initialization data 🌸
• led_classdev_name — composed LED class device name 👑

🌈 DESCRIPTION 🌈

So here’s the vibe: this function creates the LED class device name based on the init_data argument you provide 🫶. The name can be in the <devicename:color:function> form or the <color:function> form, depending on the init_data configuration. That’s it, that’s the function. ✨

0 on success, or a negative error value on failure 😭
