Subject[PATCH] kobject: fix double kobject_put in kobject_unregister()
Hi Greg,

This patch fixes the problem where in kobject resources were getting
freed when those kobject were still in use due to double kobject_put()
getting called in the kobject_unregister() code path.

With out this patch kobject_unregister() will have some serious side effects.

Please apply.
