From 29bb5d4fd3140a7d5d02d858118c74a45f15c296 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Wed, 8 Feb 2012 15:11:17 -0800 Subject: driver-core: cpu: fix kobject warning when hotplugging a cpu Due to the sysdev conversion to struct device, the cpu objects get reused when adding a cpu after offlining it, which causes a big warning that the kobject portion is not properly initialized. So clear out the object before we register it again, so all is quiet.
