of_pse_match_pi(9)

🌸 NAME 🌸

Bestie, welcome to of_pse_match_pi(9), straight outta the Kernel API Manual — and this function has one main-character job: Find the PSE PI id matching the device node phandle. That's it, that's the vibe. No cap. 💖

✨ SYNOPSIS ✨

int of_pse_match_pi (struct pse_controller_dev *pcdev , struct
       device_node *np );

🎀 ARGUMENTS 🎀

• pcdev — a pointer to the PSE controller device. Like, the controller device itself, bestie. 🫶
• np — a pointer to the device node. The device node in question. 🌸

💖 RETURN 💖

Returns the id of the PSE PI, or -EINVAL if it's not found. So the matchy-matchy path gives you the id; the not-found path is literally -EINVAL, periodt. 💅
