Frank Rowand 29acfb6559 of: unittest: kmemleak in duplicate property update ... kmemleak reports several memory leaks from devicetree unittest. This is the fix for problem 5 of 5. When overlay 'overlay_bad_add_dup_prop' is applied, the apply code properly detects that a memory leak will occur if the overlay is removed since the duplicate property is located in a base devicetree node and reports via printk(): OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail OF: overlay: WARNING: memory leak will occur if overlay removed, property: /testcase-data-2/substation@100/motor-1/rpm_avail The overlay is removed when the apply code detects multiple changesets modifying the same property. This is reported via printk(): OF: overlay: ERROR: multiple fragments add, update, and/or delete property /testcase-data-2/substation@100/motor-1/rpm_avail As a result of this error, the overlay is removed resulting in the expected memory leak. Add another device node level to the overlay so that the duplicate property is located in a node added by the overlay, thus no memory leak will occur when the overlay is removed. Thus users of kmemleak will not have to debug this leak in the future.
