platform_device_put(9)

okay so bestie 💖 welcome to platform_device_put(9) from the Kernel API Manual — lowkey tiny, highkey important, and it's giving cleanup-era main character energy. 🎀

🌸 NAME 🌸

platform_device_put — destroy a platform device. That's the whole assignment, no cap. 💅

✨ SYNOPSIS ✨

void platform_device_put (struct platform_device *pdev );

🎀 ARGUMENTS 🎀

• pdev — the platform device to free. That's the one getting the goodbye, bestie. 🫶

💅 DESCRIPTION 💅

Okay so this function frees all memory associated with a platform device. All of it. Every little byte of the vibe. 💨

But listen, because this is the part that matters: this function must _only_ be externally called in error cases. All other usage is a bug. Not a quirky little choice, not a "maybe it'll be fine," literally a bug. 😭

🚩 The rules are rules: externally in error cases only. All other usage is a bug. Periodt.
