ep_end_in_req(9)

🌸 ep_end_in_req(9) — like, the Kernel API Manual page bestie 🌸

Okay so welcome to ep_end_in_req(9), straight out of the Kernel API Manual, and no cap this page is short but it matters 💅. It's the little function that says "we're done here" to an endpoint IN request. Iconic. Let's get into it 🎀

---

✨ SYNOPSIS ✨

void ep_end_in_req (struct pxa_ep *ep , struct pxa27x_request *req ,
                    unsigned long *pflags );

That's the whole signature, bestie — copy it exactly, don't be out here renaming stuff 🙈

---

🫶 ARGUMENTS 🫶

• ep — the physical endpoint. like, the actual hardware endpoint itself, the main character 💫
• req — the pxa request. yes, that pxa request, the one you're ending 🦋
• pflags — flags from a previous spinlock_irq_save, or NULL if no lock is held. so either you got the flags or you don't, there's no in-between 🔥

---

💜 CONTEXT 💜

ep->lock held or released (see req_done). that's it, that's the vibe check — the lock situation depends on that, and req_done is where you go look 👀

---

⭐ DESCRIPTION ⭐

Ends endpoint IN request (completes usb request). literally that's the whole job 🎀 it wraps up the IN request and completes the usb request. slay, short and sweet, no notes ✨
