💅 cdns3_gadget_ep_free_request — like, the whole kernel API manual moment

okay bestie, so this is a page straight out of the Kernel API Manual, and the function we're stanning is cdns3_gadget_ep_free_request. No cap, it's a little one, but it matters 💖

✨ NAME ✨

cdns3_gadget_ep_free_request — frees the memory that a request is hogging 🫶

Like, the request had its turn, it ate, and now it's time to hand the memory back. Periodt.

🌸 SYNOPSIS 🌸

void cdns3_gadget_ep_free_request (struct usb_ep *ep , struct
       usb_request *request );

Returns void, meaning it gives you nothing back — it just vibes and does the thing. Iconic, honestly 🎀

🦋 ARGUMENTS 🦋

  • ep — the endpoint object that's associated with the request 🌈 like, who does this request belong to? That's ep.
  • request — the request itself, the one you're freeing memory for 💀 yes, this is the actual thing being deallocated.

Both of them are struct pointers and both of them are required. Not optional, bestie. Not a vibe check you can skip.
