✨ hwpath_to_device(9) ✨

okay so welcome to the Kernel API Manual, bestie 💖 this one is hwpath_to_device(9), and it's giving “find the device that matches this hardware path” energy. No cap.

🎀 NAME 🎀

hwpath_to_device — finds the generic device corresponding to a given hardware path. slay.

🌸 SYNOPSIS 🌸

struct device * hwpath_to_device (struct hardware_path *modpath );

🦋 ARGUMENTS 🦋
