Driver-Core: disable /sbin/hotplug by default
No recent mainstream system uses the /sbin/hotplug fork-bomb any more. Disable it by default to reflect how it is used these days. Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

10 Before the switch to the netlink-based uevent source, this was
11 used to hook hotplug scripts into kernel device events. It
12 usually pointed to a shell script at /sbin/hotplug.
13 This should not be used today, because usual systems create
14 many events at bootup or device discovery in a very short time
15 frame. One forked process per event can create so many processes
16 that it creates a high system load, or on smaller systems
17 it is known to create out-of-memory situations during bootup.
