💅 _pse_pi_disable(9) — Kernel API Manual, bestie edition ✨

okay so welcome to the Kernel API Manual page for _pse_pi_disable(9). This one is short, but lowkey important: it’s about the disable operation, and it comes with a lock-context assumption. No cap, let’s go 💖

🎀 NAME 🎀

_pse_pi_disable — literally “Call disable operation.” Assumes the PSE lock has been acquired.

bestie note: the PSE lock assumption is the whole vibe here — this function expects the PSE lock to already be acquired. Don’t skip that vibe check 💅

✨ SYNOPSIS ✨

Exact signature, character-for-character, because we never freestyle code:

int _pse_pi_disable (struct pse_controller_dev *pcdev , int id );

🫶 ARGUMENTS 🫶

• pcdev — a pointer to the PSE 🌸
• id — index of the PSE control 🎀

🌈 RETURN 🌈

It returns 0 on success and failure value on error. That’s the return vibe check, periodt ✨
