okay so this is straight out of the Kernel API Manual, and it's giving "tiny but important helper" energy. No cap, it's a short one, but we are keeping every crumb bestie. 🍓

🌸 NAME 🌸

es58x_submit_urb — Send data to the device. That's literally the whole job description, and honestly? Iconic. It sends data to the device, periodt. 💖

✨ SYNOPSIS ✨

int es58x_submit_urb (struct es58x_device *es58x_dev , struct urb *urb ,
       struct net_device *netdev );

🦋 ARGUMENTS 🦋

• es58x_dev — ES58X device. The ES58X device itself, your main-character struct. 💅
• urb — URB to be sent. The actual URB going out into the world. ✨
• netdev — CAN network device. The CAN network device in question. 🎀

🔥 RETURN 🔥

zero on success — slay — and errno when any error occurs. That's the whole return story, no cap. 😭
