💅 bcm63xx_udc_dequeue — bestie's guide to yeeting a request out of the queue

Okay so real talk, this is a page straight out of the Kernel API Manual, and today we're deep in the USB gadget driver trenches. Buckle up, it's giving kernel-nerd slay ✨

---

✨ NAME ✨

bcm63xx_udc_dequeue — literally just removes a pending request from the queue. That's it. That's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

int bcm63xx_udc_dequeue (struct usb_ep *ep , struct usb_request *req );

---

🦋 ARGUMENTS 🦋

• ep — the endpoint that's hanging out with this request, like its emotional support endpoint fr fr 🫶
• req — the request you want gone. bye bestie 👋

---

💖 DESCRIPTION 💖

okay so here's the tea ☕ — it depends on where the request is sitting in the queue:

• Not at the head of the queue? easy mode, lowkey a breeze — just nuke it. 💀✨
• At the head of the queue? now we're in main character territory 😭 we can't just vibe it out of existence, we have to stop the DMA transaction first, and then queue up the successor. the way that's so much more work for one little request, honestly 🙈
