phy_save_page(9)

🌸 phy_save_page — NAME 🌸

phy_save_page 💅 — bestie, it grabs the bus lock and saves whatever page you're currently on ✨

---

✨ SYNOPSIS ✨

int phy_save_page (struct phy_device *phydev );

---

🎀 ARGUMENTS 🎀

• phydev — a pointer to a struct phy_device 🫶 (yes it's literally just the one argument, she's low maintenance, we love her)

---

💖 DESCRIPTION 💖

okay so here's the whole vibe 👑: phy_save_page takes the MDIO bus lock and then returns the current page number. That's it. That's the whole job. Iconic, honestly.

If something goes sideways, it returns a negative errno instead 😭 — so do your vibe check on that return value, ngl.

🚨 real talk, this is the important part: phy_restore_page must always be called after this — irrespective of success or failure of this call. Like, no cap, always. Success, failure, whatever — you still call phy_restore_page. Don't leave her hanging bestie 💀
