✨ usb_driver_release_interface(9) ✨

okay so real quick β€” welcome to the Kernel API Manual, bestie πŸŽ€ this one's a tiny little function with a big job, and honestly? it's giving "short but powerful" energy. let's get into it πŸ’…


🌸 NAME 🌸

usb_driver_release_interface β€” unbind a driver from an interface

like, literally just let go. that's the whole vibe πŸ¦‹


✨ SYNOPSIS ✨

void usb_driver_release_interface (struct usb_driver *driver , struct
       usb_interface *iface );

no return value, no drama. it's a void function fr fr πŸ’œ


πŸ’– ARGUMENTS πŸ’–

  • driver β€” the driver to be unbound πŸ‘‹ this is the one getting let go
  • iface β€” the interface from which it will be unbound 🎯 this is where the letting-go happens

πŸ¦‹ DESCRIPTION πŸ¦‹

so here's the tea β˜• β€” this function lets drivers release an interface without sitting around waiting for their disconnect methods to get called. main character energy: it takes initiative 🫢

and in typical cases? this also causes the driver disconnect method to be called anyway. so like, the disconnect still shows up to the party, it just didn't have to be invited first πŸ™ˆ

⚠️ important warning bestie ⚠️ this call is synchronous, and it may not be used in an interrupt context. no cap, do not try it. 😭

callers must own the device lock β€” which is actually kinda slay, because it means driver disconnect entries don't need extra locking πŸ”₯ but other call contexts may need to explicitly claim that lock themselves. so, y'know, check your context before you vibe check the lock πŸ’€

this iconic lil entry lives under ./drivers/usb/core and it's stamped October 2026 β€” so like, mark your calendars, screenshot it, put it on your fridge 🧚 mwah, go release some interfaces responsibly πŸ’…πŸ’–
