Summary

In the Linux kernel, the following vulnerability has been resolved: platform/chrome: cros_ec_ishtp: Fix UAF after unbinding driver After unbinding the driver, another kthread `cros_ec_console_log_work` is still accessing the device, resulting an UAF and crash. The driver doesn't unregister the EC device in .remove() which should shutdown sub-devices synchronously. Fix it.
