|dev is the device that owns the resource.|
|type is the type of resource that is released. It must be of the same type you allocated it as before. See bus_alloc_resource(9) for valid types.|
|rid is the resource ID of the resource. The rid value must be the same as the one returned by bus_alloc_resource(9).|
|r is the pointer to struct resource, i.e., the resource itself, returned by bus_alloc_resource(9).|
EINVAL is returned, if the device dev has no parent, 0 otherwise. The kernel will panic, if it cannot release the resource.
