platform/chrome: cros_ec_debugfs: Unregister panic notifier
In the Linux kernel, the following vulnerability has been resolved: platform/chrome: cros_ec_debugfs: Unregister panic notifier cros_ec_debugfs_probe() registers notifier_panic with the EC panic notifier chain. The remove path tears down debugfs and the console log, but leaves the notifier registered. A later panic notification can call back into the removed instance and queue work that accesses released data. Unregister the panic notifier before tearing down the debugfs and console log state. This issue was found by a static analysis tool.
