/*
* &electric_1/motor-1/electric and &spin_ctrl_1/electric are the same node:
* /testcase-data-2/substation@100/motor-1/electric
*
* Thus the property "rpm_avail" in each fragment will
* result in an attempt to update the same property twice.
* This will result in an error and the overlay apply
* will fail.
*
* The previous version of this test did not include the extra
* level of node 'electric'. That resulted in the 'rpm_avail'
* property being located in the pre-existing node 'motor-1'.
* Modifying a property results in a WARNING that a memory leak
* will occur if the overlay is removed. Since the overlay apply
* fails, the memory leak does actually occur, and kmemleak will
* further report the memory leak if CONFIG_DEBUG_KMEMLEAK is
* enabled. Adding the overlay node 'electric' avoids the
* memory leak and thus people who use kmemleak will not
* have to debug this non-problem again.
