1. NAME▲

device_unregister - unregister device from system.

2. SYNOPSIS ▲

void device_unregister(struct device *  dev );

3. ARGUMENTS ▲

dev
    device going away.

4. DESCRIPTION ▲

We do this in two parts, like we do device_register. First, we remove it from all the subsystems with device_del, then we decrement the reference count via put_device. If that is the final reference count, the device will be cleaned up via device_release above. Otherwise, the structure will stick around until the final reference to the device is dropped.
