STRUCT OMNIA_LEDS(9)

💖 struct omnia_leds(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little struct deep-dive from the kernel world, and honestly? it's giving "backstage pass to the LED driver" 🎀

---

🌸 NAME 🌸

struct omnia_leds — the driver's very own private data structure. like, this is her diary, nobody else reads it 💅

---

✨ SYNOPSIS ✨

struct omnia_leds {
    struct i2c_client *client;
    struct mutex lock;
    bool has_gamma_correction;
    struct kernfs_node *brightness_knode;
    struct omnia_led leds[];
 };

lowkey iconic little struct ngl 🦋

here's the cast, one by one, main character energy all around 👑

• client — the I2C client device. that's her connection to the hardware, fr fr 😌
• lock — a mutex whose whole job is protecting the cached state. do NOT skip the lock bestie, that's how you get chaos 💀
• has_gamma_correction — a bool that tells you whether the MCU firmware supports gamma correction or not. yes/no, slay or nay 🌈
• brightness_knode — the kernel node of the "brightness" device sysfs attribute. and listen, this is the driver specific global brightness, not the LED classdev brightness — don't mix them up, iykyk 🙈
• leds — a flexible array of per-LED data. flexible = she grows, she adapts, she's that girl 🌸

ngl this struct is short but she's doing a LOT of work behind the scenes 🧚

that's the whole page, bestie — you ate it up 💅✨

shoutout to ./drivers/leds, stamped October 2026, living in struct omnia_leds(9) — see you in the next manpage, mwah 🎀
