🎀 NAME 🎀

__devm_uio_register_device — Resource managed uio_register_device()

🌸 SYNOPSIS 🌸

the signature is literally this, don't @ me:

int __devm_uio_register_device (struct module *owner , struct device *parent , struct uio_info *info );

🦋 ARGUMENTS 🦋

• owner — the module that creates the new device. main character module energy. 👑
• parent — the parent device. it's giving family tree. 🌳
• info — the UIO device capabilities. the whole vibe sheet. ✨

💖 DESCRIPTION 💖

return value check: it returns zero on success or a negative error code. that's the tea ☕ — success is 0, and anything negative is the error-code part. no extra lore needed. 💀
