platform_device_unregister(9)

💅 platform_device_unregister(9) ✨

okay bestie, welcome to the Kernel API Manual — this one's about platform_device_unregister, and yes it's as iconic as it sounds 🎀

---

🌸 NAME

platform_device_unregister — unregister a platform-level device 🫶

---

✨ SYNOPSIS

void platform_device_unregister (struct platform_device *pdev );

---

🦋 ARGUMENTS

• pdev — the platform device we're unregistering, aka the main character we're sending off 👋

---

💖 DESCRIPTION

okay so the unregistration does NOT happen all at once, it's a whole two-step moment, and honestly? it's giving choreography 💅

1. first we release all the resources and remove it from the subsystem 🔥
2. then we drop the reference count by calling platform_device_put 💜

two steps, no skipping, no cap. slay.
