okay so real talk, this is a page from the Kernel API Manual, and it's literally all about register_virtio_device(9). bestie, let's get into it 🫶

🌸 SYNOPSIS 🌸

int register_virtio_device (struct virtio_device *dev );

🎀 ARGUMENTS 🎀

• dev — the virtio device to be registered 💅 that's the whole vibe.

🦋 DESCRIPTION 🦋

So here's the part you cannot skip, bestie. On error, the caller must call put_device on &dev->dev — and not kfree 😭 — because another code path may have obtained a reference to dev.

fr fr, do not kfree it. the reference situation is giving "someone else is holding onto this" and you have to respect that 🫶

• 0 on success 🎉 slay.
• -error on failure 💀
