gpiochip_get_data(9)

✨ gpiochip_get_data(9) ✨

Okay bestie, we're in the Kernel API Manual and this function is literally the "hand me my stuff" icon of the GPIO world. 🫶 It's tiny, it's specific, and it absolutely ate.

---

💖 NAME 💖

gpiochip_get_data — get per-subdriver data for the chip

---

🌸 SYNOPSIS 🌸

void * gpiochip_get_data (struct gpio_chip *gc );

---

🎀 ARGUMENTS 🎀

• gc — GPIO chip. That's the chip you're pulling the data from, bestie. 💅

---

🦋 RETURN 🦋

The per-subdriver data for the chip. Yep — that's the whole return vibe. It hands you back the per-subdriver data for the chip, and that is genuinely the entire plot. ✨
