-EINVAL doesn't translate to "bool" too well...

In the spirit of my comment on patch 1 and consistency, instead perhaps
just read this fuse at boot, and assign it to a global?
BTW, why the need for "? true : false" - doesn't the compiler do the
conversion correctly itself. Perhaps it's to avoid a performance
warning, in which case a leading !! seems to be more popular.
