👑 NAME 👑

Okay bestie, welcome to the Kernel API Manual entry for input_ff_erase — it literally erases a force-feedback effect from a device. Periodt. 💅

✨ SYNOPSIS ✨

int input_ff_erase (struct input_dev *dev , int effect_id , struct file
       *file );

🎀 ARGUMENTS 🎀

• dev — the input device you're erasing the effect from, bestie.
• effect_id — the id of the effect that's getting erased.
• file — the purported owner of the request 👀

💖 DESCRIPTION 💖

This function erases a force-feedback effect from the specified device. The effect will only be erased if it was uploaded through the same file handle that is requesting the erase. No cap — that ownership check is the whole vibe. 🫶
