STRUCT KEYBOARD_LED_DRVDATA(9)

🌸 NAME 🌸

okay so bestie, welcome to the Kernel API Manual ✨ — this page is literally about struct keyboard_led_drvdata, aka keyboard LED driver data. periodt. 💅

✨ SYNOPSIS ✨

here's the struct in all its iconic glory, copied exactly so we don't break anything:

       struct keyboard_led_drvdata {
           int (*init)(struct platform_device *pdev, struct keyboard_led
       *keyboard_led);
           enum led_brightness (*brightness_get)(struct led_classdev
       *led_cdev);
           void (*brightness_set)(struct led_classdev *led_cdev, enum
       led_brightness brightness);
           int (*brightness_set_blocking)(struct led_classdev *led_cdev, enum
       led_brightness brightness);
        };

🎀 Members 🎀

• init — Init function. 🛠️
• brightness_get — Get LED brightness level. 🔆
• brightness_set — Set LED brightness level. Must not sleep. ⚠️ like, do not let this function catch Zs, no cap.
• brightness_set_blocking — Set LED brightness level. It can block the caller for the time required for accessing a LED device register. ⏳ yes, it can literally block — that's the whole vibe.

🦋 Description 🦋

See struct led_classdev in include/linux/leds.h for more details. ✨
