💅 usb_deregister — unregister a USB interface driver ✨

Okay bestie, so this one is from the Kernel API Manual (section 9 of the man pages, iykyk) and it's literally the undo button for a USB interface driver. Short page, but every detail matters, so let's go 🫶

🌸 SYNOPSIS 🌸

void usb_deregister (struct usb_driver *driver );

🎀 ARGUMENTS 🎀

  • driver — the USB operations of the interface driver you're unregistering. Like, the driver itself, bestie, hand it over 💅

💖 CONTEXT 💖

must be able to sleep 😴

Fr fr — this call is allowed to sleep, so don't go calling it from somewhere that can't, mwah.

✨ DESCRIPTION ✨

It unlinks the specified driver from the internal USB driver list. That's the whole vibe — you're detaching it from the kernel's little driver guest list 👑

🔥 NOTE 🔥

Huge one, don't skip this 🙈 — if you called usb_register_dev, you still need to call usb_deregister_dev to clean up your driver's allocated minor numbers. This * call will no longer do it for you. Like, it used to, and now it doesn't. Character development 💀

🌈 SEE ALSO 🌈
