phy_put(9)

💅 phy_put(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, that's the manual name, and yes, we're reading it together, hold my hand 🫶

---

🌸 NAME 🌸

phy_put — release the PHY, that's literally it, that's the whole job ✨

---

🦋 SYNOPSIS 🦋

void phy_put (struct device *dev , struct phy *phy );

no cap, that's the entire signature. two args, void return, in and out, done 💅

---

🎀 ARGUMENTS 🎀

• dev — the device that wants to release this phy. it's giving "hey, I'm done with this, take it back" energy 👑
• phy — the phy returned by phy_get. important!! this is the one you got back from phy_get, not some random phy you found lying around 🙈

---

💖 DESCRIPTION 💖

so what it actually does: it releases a refcount the caller received from phy_get.

that's it. that's the vibe check. you took a ref, now you're giving it back. balanced. symmetrical. main character energy for your reference counting ngl ⭐

bestie please actually pair this with your phy_get — an unmatched ref is not the slay you think it is 😭
