gpio_chrdev_release(9)

🌸 NAME 🌸

okay bestie, this is gpio_chrdev_release(9), straight from the Kernel API Manual — and its whole job is literally to close the chardev after the ioctl operations are done. no cap, that's the vibe. 💅

✨ SYNOPSIS ✨

here's the signature, copied exactly because we do not mess with code, ever:

int gpio_chrdev_release (struct inode *inode , struct file *file );

🎀 ARGUMENTS 🎀

• inode — the inode for this chardev. yes ma'am, that exact inode. 🦋
• file — the file struct for storing private data. it's giving "private data goes here" energy. 🫶

⭐ RETURN ⭐

• 0 on success, or a negative errno on failure. slay if it's 0, cry in errno if it's not 😭

🦋 SEE ALSO 🦋

• Kernel file ./drivers/gpio/gpiolib-cdev.c
• struct linehandle_state(9)
• struct line(9)
• struct linereq(9)
• struct lineevent_state(9)
• gpio_chrdev_open(9)

bestie, that's all the SEE ALSO lore the page gives — the kernel file plus those structs and gpio_chrdev_open(9). go read them if you want the full ecosystem moment. 🧚

💌 ok bye bestie — source/version: ./drivers/gpio; date: October 2026; page: gpio_chrdev_release(9). mwah 💋
