yt8521_read_page(9)

💅 yt8521_read_page — like, the Kernel API Manual one 🎀

okay so bestie, gather round, because we're diving into yt8521_read_page from the ✨Kernel API Manual✨ and honestly? it's giving tiny-but-powerful. no cap. 🦋

---

🌸 NAME 🌸

yt8521_read_page — read reg page. that's it. that's the whole vibe. short, sweet, iconic. 👑

---

✨ SYNOPSIS ✨

int yt8521_read_page (struct phy_device *phydev );

look at her. one function, one argument, zero drama. we love a low-maintenance queen. 💅

---

🎀 ARGUMENTS 🎀

• phydev — a pointer to a struct phy_device. yes bestie, it's a pointer. it points at a phy_device struct. that's the whole assignment and she ate. 🫶

---

🌈 DESCRIPTION 🌈

so what does she actually do? she returns the current reg space of yt8521 — and it's gonna be one of these two besties:

• YT8521_RSSR_FIBER_SPACE
• YT8521_RSSR_UTP_SPACE

...or, if things are not slaying, a negative errno code. 😭 that's the whole deal. no hidden lore, no plot twist, fr fr. 🔥

ngl, if you get a negative errno back, that's your sign that something went sideways — treat it as the error whisper it is. 💀
