Greg Kroah-Hartman 014c90dbb9 driver core: prevent device_for_each_child from oopsing
David Vrabel noticed that the wireless usb stack likes to call
device_for_each_chile() with an empty bus.  This used to work fine, but
now oopses.  This patch fixes the oops and makes the code behave like it
used to.
