## Overview

In the Linux kernel, the following vulnerability has been resolved:

remoteproc: scp: Fix device reference leak on failed lookup

Make sure to drop the reference taken to the SCP device when attempting
to look up its driver data before the driver has been bound.

Note that holding a reference to a device does not prevent its driver
data from going away.
