James Bottomley cc9b2e9f66 [SCSI] enclosure: fix oops while iterating enclosure_status array
Based on patch originally by Jeff Mahoney <jeffm@suse.com>

 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.

James Bottomley 43d8eb9cfd [SCSI] ses: add support for enclosure component hot removal
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

James Bottomley 163f52b6cf [SCSI] ses: fix hotplug with multiple devices and expanders
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).

Tony Jones ee959b00c3 SCSI: convert struct class_device to struct device
It's big, but there doesn't seem to be a way to split it up smaller...

James Bottomley d569d5bb3f [SCSI] enclosure: add support for enclosure services
The enclosure misc device is really just a library providing sysfs
support for physical enclosure devices and their components.
