✨ yt8821_serdes_init(9) — the kernel API glow-up ✨

okay so bestie, this one's a kernel API manual page from ./drivers/net/phy, and we're talking about yt8821_serdes_init — the serdes init function. yes it's a real one. it's giving "tiny function, very serious job" energy and honestly? iconic. 🎀

🌸 NAME 🌸

yt8821_serdes_init — serdes init. that's it. that's the whole name. short, sweet, knows exactly what it is. 👑

---

✨ SYNOPSIS ✨

int yt8821_serdes_init (struct phy_device *phydev );

look at her. one argument, returns an int. lowkey elegant ngl. 💅

---

🦋 ARGUMENTS 🦋

• phydev — a pointer to a struct phy_device. that's the whole vibe check. she gets handed a pointer to the phy device and she does her serdes init thing with it. 🫶

---

🌈 RETURN 🌈

0 or negative errno code. so like — zero means slay, negative means something went sideways and you get an errno code telling you why. no cap. 😭

heads up bestie: it's 0 or a negative errno code, not just any random int. don't come for me.
