input_mt_destroy_slots(9)

💅 NAME 💅

ok so input_mt_destroy_slots — she literally frees the MT slots of the input device 🦋 that's it, that's her whole job, and she's iconic for it

✨ SYNOPSIS ✨

void input_mt_destroy_slots (struct input_dev *dev );

🎀 ARGUMENTS 🎀

• dev — the input device that has the allocated MT slots, bestie 💖 this is literally the thing you're handing over so the slots can get freed

🌸 DESCRIPTION 🌸

okay so here's the tea, and it's important: you only need this function in the error path 🫶 like, that's the only scenario. because the input core is a whole main character and will automatically free the MT slots when the device is destroyed anyway 😭 no cap, she handles it herself.

so if you're sitting there like "hmm do I need to call this" — the answer is basically only when something went wrong on the way in, bestie 💀 don't be doing extra work for no reason
