of: overlay: unittest: add tests for overlay notifiers
Add tests for overlay apply and remove notifiers. Trigger errors for each of the notifier actions. These tests will reveal a memory leak problem when a notifier returns an error for action OF_OVERLAY_POST_APPLY. The pr_err() message is: OF: ERROR: memory leak, expected refcount 1 instead of 3, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /testcase-data/overlay-node/test-bus/test-unittest17 Signed-off-by: Frank Rowand <frank.rowand@sony.com> Signed-off-by: Rob Herring <robh@kernel.org> Link: https://lore.kernel.org/r/20220502181742.1402826-3-frowand.list@gmail.com
