Subject: Re: [PATCH 1/2] rpmb: stop the routing after unregister

> OP-TEE has a reference of RPMB device it used. So, it can route
> frames through the device after rpmb_dev_unregister() is called.
> Therefore, the parent device passed to route_frames() can be
> already freed, for example, mmc_blk_remove_rpmb_part() drops the
> last reference after rpmb unregister.
>
> This patch clears the route_frames when the device is going to
> be removed by getting new rwsem and makes rpmb_route_frames()
> return -ENODEV if the device is gone.
