-Subject: [PATCH 05/20] asus-wmi: Restrict debugfs interface when module
- loading is restricted
-
-We have no way of validating what all of the Asus WMI methods do on a
-given machine, and there's a risk that some will allow hardware state to
-be manipulated in such a way that arbitrary code can be executed in the
-kernel, circumventing module loading restrictions. Prevent that if any of
-these features are enabled.
