kobject: convert /sys/hypervisor to use kobject_create
We don't need a kset here, a simple kobject will do just fine, so dynamically create the kobject and use it. We also rename hypervisor_subsys to hypervisor_kset to catch all users of the variable. Cc: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
