phy_module_driver(9)

💅 phy_module_driver — a Kernel API Manual moment (yes, from phy_module_driver(9), we're fancy)

okay so bestie, picture this: you wrote a PHY driver, it's gorgeous, it's iconic, and now you need the kernel to actually register it. that's the whole job of this macro. it's the "just do the normal thing for me" button. ✨

---

🌸 NAME 🌸

phy_module_driver — the helper macro for registering PHY drivers. that's it. that's the name. 🎀

---

🦋 SYNOPSIS 🦋

phy_module_driver (__phy_drivers , __count );

literally just drop it in your file like that, no cap.

---

💖 ARGUMENTS 💖

• __phy_drivers — the array of PHY drivers you wanna register. your whole little squad of drivers, in array form. 👑
• __count — the number of members in that array. yes you have to count them. no the macro won't do it for you. it's giving "do your own homework". 😭

---

🔥 DESCRIPTION 🔥

so this is the helper macro for PHY drivers that don't do anything special in module init/exit. like, nothing extra, no little send-off ritual, just vibes and registration. 🫶

⚠️ each module may only use this macro once. one time. single use. and calling it replaces module_init and module_exit — so don't go doubling up, that's not the move. 💀
