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

mei: bus: access mei_device under device_lock on cleanup

Fix couple of problems in mei_cl_bus_dev_release():

mei_cl_flush_queues() is running without lock.
bus->file_list access after mei_dev_bus_put(bus) can become a
use-after-free if this was the last reference to bus.

Protect queues cleanup and WARN traversal by device lock there
to avoid the concurrent access problems.
Move WARN traversal before mei_dev_bus_put(bus).

This file uses bus variable name for mei_device, adjust
code of mei_cl_bus_dev_release() to use bus variable too.
