mei: bus: access mei_device under device_lock on cleanup
Overview
Description
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.

Solution
Address race conditions in mei_cl_bus_dev_release by acquiring the device lock during cleanup.
- Acquire device lock before cleaning up queues.
- Move WARN traversal before device bus put.
- Update code to use 'bus' variable name.
- Apply the latest kernel patches.
