✨ es58x_alloc_rx_urbs(9) ✨

Okay so bestie, welcome to the Kernel API Manual 💖 — yes, the kernel has manuals, and yes, this one is a whole vibe. It's all about es58x_alloc_rx_urbs, which is lowkey the function that gets your ES58X's receive side set up. Let's get into it 🎀

---

🌸 NAME 🌸

es58x_alloc_rx_urbs — Allocate RX URBs. That's it, that's the whole thing. Short and iconic 💅

---

🦋 SYNOPSIS 🦋

int es58x_alloc_rx_urbs (struct es58x_device *es58x_dev );

---

🌈 ARGUMENTS 🌈

• es58x_dev — the ES58X device in question, obvs. This is the device you're doing the allocating for 🫶

---

💜 DESCRIPTION 💜

So what does it do? It allocates URBs for reception and then anchors them. That's the whole deal ✨ Receive URBs get allocated, and they get anchored — done. Ngl, it's a short description but she ate and left no crumbs 💀

---

⭐ RETURN ⭐

• zero on success 🎉
• errno when any error occurs 😭 (so like, check the return value, bestie, fr fr)

💡 Real talk: this page is from the ./drivers/net/can/usb/etas_es58x directory, October 2026 edition, in the Kernel API Manual. That's the whole sign-off bestie — now go allocate those URBs and slay 💅✨🎀
