Subject: kobject: convert /sys/hypervisor to use kobject_create
X-Git-Tag: v2.6.25-rc1~1243^2~132
X-Git-Url: http://pilppa.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=2d72fc00a1fb055e6127ccd30cac3f0eafaa98d0;p=linux-2.6-omap-h63xx.git

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.
