✨ arc_mdio_probe(9) ✨

okay so this is a page from the Kernel API Manual and it's all about arc_mdio_probe, bestie. it's giving "small function, big job" energy and honestly? we love that for it 🎀

💅 NAME 💅

arc_mdio_probe — the MDIO probe function, aka the little matchmaker that gets your MDIO interface set up and registered 💖

---

🌸 SYNOPSIS 🌸

int arc_mdio_probe (struct arc_emac_priv *priv );

like, it takes exactly one thing and returns an int. no drama, no surprises, periodt ✨

---

🦋 ARGUMENTS 🦋

• priv — a pointer to the ARC EMAC private data structure 🫶 that's the one (and only) thing it wants from you.

---

🌈 RETURN 🌈

• 0 — success, we ate, everything's iconic 👑
• -ENOMEM — this is what you get when mdiobus_alloc fails. and what does mdiobus_alloc do? it allocates memory for the MII bus structure, so if there's no memory to give, yeah, that's a -ENOMEM moment 😭

---

🔥 DESCRIPTION 🔥

it sets up and registers the MDIO interface. that's the whole vibe. short, sweet, gets the job done 💜
