💖 DESCRIPTION 💖

okay so here's the tea ☕: viodev is a pointer to the struct vio_dev for the device you're dealing with.

What this function does is remove the device from the cmo device list. and here's the important part, so pay attention 👑

The minimum entitlement will be reserved for the device for as long as it is in the system. like, it keeps that baseline no matter what, periodt.

The rest of the entitlement that the device had been allocated? yeah, that gets returned to the system. giving back what's not needed, we love a generous icon 🌈💸
