As by now, platform::Device is implemented as:
#[derive(Clone)]
pub struct Device(ARef<device::Device>);
This may be convenient, but has the implication that drivers can call
device methods that require a mutable reference concurrently at any
point of time.
Instead define platform::Device as
pub struct Device<Ctx: DeviceContext = Normal>(
Opaque<bindings::platform_dev>,
PhantomData<Ctx>,
);
and manually implement the AlwaysRefCounted trait.
With this we can implement methods that should only be called from
bus callbacks (such as probe()) for platform::Device<Core>. Consequently,
we make this type accessible in bus callbacks only.
Arbitrary references taken by the driver are still of type
ARef<platform::Device> and hence don't provide access to methods that are
reserved for bus callbacks.
