Based on patch originally by Jeff Mahoney <[email protected]>
enclosure_status is expected to be a NULL terminated array of strings
but isn't actually NULL terminated. When writing an invalid value to
/sys/class/enclosure/.../.../status, it goes off the end of the array
and Oopses.
Fix by making the assumption true and adding NULL at the end.

Right at the moment, hot removal of a device within an enclosure does
nothing (because the intf_remove only copes with enclosure removal not
with component removal). Fix this by adding a function to remove the
component. Also needed to fix the prototype of
enclosure_remove_device, since we know the device we've removed but
not the internal component number

In a situation either with expanders or with multiple enclosure
devices, hot add doesn't always work. This is because we try to find
a single enclosure device attached to the host. Fix this by looping
over all enclosure devices attached to the host and also by making the
find loop recognise that the enclosure devices may be expander remote
(i.e. not parented by the host).

The enclosure misc device is really just a library providing sysfs
support for physical enclosure devices and their components.
