gpiochip_remove(9)

✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual page for gpiochip_remove(9). Its whole personality is: unregister a gpio_chip. that's the name, that's the job, it's giving "bye chip" energy and honestly? iconic. 💅

🛠️ SYNOPSIS 🛠️

void gpiochip_remove (struct gpio_chip *gc );

🎀 ARGUMENTS 🎀

• gc — the chip to unregister. literally the gpio_chip you're saying bye to. no extra quests, no hidden params. 🫶

🌸 DESCRIPTION 🌸

A gpio_chip with any GPIOs still requested may not be removed.

🚨 so yeah, if even one GPIO on that chip is still requested, removal is a hard no. the rule says it may not be removed. periodt. 💀

okay that's the page, bestie 💖 it lives in ./drivers/gpio, dated October 2026, and it's literally the gpiochip_remove(9) manual page. mwah 💋
