| H A D | iicsmb.c | diff 289657 Tue Oct 20 18:04:58 MDT 2015 dumbbell iicbus: Use device_delete_children() instead of explicit child removal If the bus is detached and deleted by a call to device_delete_child() or device_delete_children() on a device higher in the tree, I²C children were already detached and deleted. So the device_t pointer stored in sc points to freed memory: we must not try to delete it again. By using device_delete_children(), we let subr_bus.c figure out if there are children to take care of. While here, make sure iicbus_detach() and iicoc_detach() call device_delete_children() too, to be safe.
