fwnode_phy_find_device(9)

🦋 fwnode_phy_find_device(9) 🦋

okay bestie, welcome to the Kernel API Manual page for fwnode_phy_find_device(9) — this is the PHY-finding glow-up and we are getting into it. ✨

💖 NAME 💖

fwnode_phy_find_device — for the provided phy_fwnode, find phy_device. That's the whole mission, no cap. 👑

🌸 SYNOPSIS 🌸

struct phy_device * fwnode_phy_find_device (struct fwnode_handle
       *phy_fwnode );

🎀 ARGUMENTS 🎀

• phy_fwnode — pointer to the phy's fwnode. That's the input, bestie; hand it over and let the function do its thing. 💅

🔥 DESCRIPTION 🔥

If it's successful, it returns a pointer to the phy_device with the embedded struct device refcount incremented by one. If it's not successful? You get NULL on failure. That's the vibe check: real pointer with the refcount bumped by one, or NULL. 😭

🌈 SEE ALSO 🌈
