dp_aux_ep_probe(9)

🎀 NAME 🎀

okay so bestie, this is dp_aux_ep_probe(9) from the Kernel API Manual, and it’s literally the probe function for the dp_aux_bus. it’s giving “tiny callback, big main character energy,” and no cap, you’re gonna get it. 💅✨

🌸 SYNOPSIS 🌸

int dp_aux_ep_probe (struct device *dev );

🦋 ARGUMENTS 🦋

• dev — the device to probe. that’s the whole argument, and she ate. 💖

🍓 DESCRIPTION 🍓

this one is lowkey simple: it calls through to the endpoint driver probe. periodt. no extra side quests, just handing the probe vibes over to the endpoint driver. 🔥

💜 RETURN 💜

• 0 if no error, or a negative error code

like, success is 0, and anything negative is the kernel saying “bestie, no 😭”. fr fr, keep that in mind.
