This bug still exists in 2.6.32-rc6.
It's pretty crazy - if we use a legal value then the routine correctly
returns -EINVAL as there is no setter.
If we write an illegal value to status we get an oops!
Aha! It's because the enclosure_status array is not NULL terminated, so
if we try to write an illegal value we run off the end of the array!
