[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. Reported-by: Artur Wojcik <artur.wojcik@intel.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
