devm_mdiobus_alloc_size(9)

💅 devm_mdiobus_alloc_size(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes this is literally the devm_mdiobus_alloc_size(9) page and it's giving "tiny function, big responsibility" energy. let's get into it 🎀

---

✨ NAME ✨

devm_mdiobus_alloc_size — the resource-managed glow-up of mdiobus_alloc_size(). same girl, but now she cleans up after herself 🫶

---

🌸 SYNOPSIS 🌸

struct mii_bus * devm_mdiobus_alloc_size (struct device *dev , int sizeof_priv );

that's the whole vibe: you hand her a dev, you hand her a size, she hands you back a struct mii_bus *. slay ✨

---

🦋 ARGUMENTS 🦋

• dev — the device you're allocating the mii_bus for. main character energy, everything hangs off this one 💖
• sizeof_priv — the space to allocate for your private structure. lowkey the extra room in the back of the bus, iykyk 🚌

---

🌈 DESCRIPTION 🌈

so it's a managed mdiobus_alloc_size. the mii_bus you allocate with this function gets automatically freed on driver detach — like, you don't have to do anything, it's handled, no cap 🙈

literally the whole point: allocate now, forget later, the kernel remembers for you. it's giving "she's so organized" 💅

---

⭐ RETURN ⭐

• pointer to the allocated mii_bus on success 🔥
• NULL on out-of-memory error 😭 (yeah, check it. please check it.)

---

🧚 SEE ALSO 🧚

• Kernel file ./drivers/net/phy/mdio_devres.c 📁
• __devm_mdiobus_register(9)
• __devm_of_mdiobus_register(9)

ok that's the whole page bestie, go forth and allocate responsibly 💜
