/*
|
|
* &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.
