💅 of_phy_find_device(9) 💅

okay so bestie, this one is straight out of the Kernel API Manual, and it’s the page for of_phy_find_device(9). it’s short, it’s useful, and it’s giving “tiny function, big main character energy.” 💖

✨ NAME ✨

of_phy_find_device — give a PHY node, find the phy_device

🦋 SYNOPSIS 🦋

struct phy_device * of_phy_find_device (struct device_node *phy_np );

🎀 ARGUMENTS 🎀

• phy_np — a pointer to the PHY’s device tree node. literally the node. that’s the vibe. 🌸

💖 DESCRIPTION 💖

so here’s the tea: if it works, this function returns a pointer to the phy_device, and the embedded struct device refcount gets incremented by one. slay. 🫶

if it does not work, you get NULL on failure. no cap. 💀
