Hello, Matthew.

I consider this one a serious bug and with a trivial fix that should go
to Linus, for the next release candidate. I also consider it should go
to stable releases, and that's why I'm copying stable.

Any out-of-tree wmi driver written for systems with two or more GUIDs
containing any '\0' byte with a common prefix will fail to load because
of this bug. I've hit that, and that's how I found the bug.

Regards,
Cascardo.
