[PATCH] remove CONFIG_KOBJECT_UEVENT option
It makes zero sense to have hotplug, but not the netlink events enabled today. Remove this option and merge the kobject_uevent.h header into the kobject.h header file. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
