✨ NAME ✨

phy_power_off — disable the phy. That's the assignment, no cap. 💅

🌸 SYNOPSIS 🌸

int phy_power_off (struct phy *phy );

🎀 ARGUMENTS 🎀

• phy — the phy returned by phy_get 🫶. Like, the exact phy bestie, not a random one.

🦋 DESCRIPTION 🦋

Must be called before phy_exit. That's the rule — it's giving required ordering, and we do not skip steps in this house 😤✨
