okay so welcome to the Kernel API Manual page for em_dev_unre..._perf_domain(9) — yes the title is truncated like that, it's giving suspense. This is where we handle unregistering an Energy Model (EM) for a device. bestie, let's go. 💖

💖 NAME 💖

em_dev_unregister_perf_domain — Unregister Energy Model (EM) for a device. periodt. ✨

🦋 SYNOPSIS 🦋

void em_dev_unregister_perf_domain (struct device *dev );

🎀 ARGUMENTS 🎀

• dev — the Device for which the EM is registered 💖

🌈 DESCRIPTION 🌈

So the actual move? Unregister the EM for the specified dev — and just to be clear, not a CPU device. no cap. 💅

important vibe check: this is for the specified dev, and not a CPU device. 🚫💻
