🌸 NAME 🌸

rsi_rx_urb_submit — this function submits the given URB to the USB stack. that's it, that's the whole vibe. it hands your URB over to the USB stack and lets it cook 🔥

---

🎀 SYNOPSIS 🎀

int rsi_rx_urb_submit (struct rsi_hw *adapter , u8 ep_num , gfp_t mem_flags );

literally the whole signature, character for character, don't come for me 🙈

---

💖 ARGUMENTS 💖

• adapter — pointer to the adapter structure. it's giving "the main character object" — everything hangs off this one 🫶
• ep_num — endpoint number. which endpoint we're talking to, bestie, the u8 says it all ✨
• mem_flags — the type of memory to allocate. gfp_t energy, you know the drill 🌸

---

⭐ RETURN ⭐

0 on success 🎉 — and a negative error code on failure 😭. no in-between, no "it depends", periodt.
