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

# Apply overlays statically with fdtoverlay. This is a build time test that
|
|
# the overlays can be applied successfully by fdtoverlay. This does not
|
|
# guarantee that the overlays can be applied successfully at run time by
|
|
# unittest, but it provides a bit of build time test coverage for those
|
|
# who do not execute unittest.
|
|
#
|
|
# The overlays are applied on top of static_base_1.dtb and static_base_2.dtb to
|
|
# create static_test_1.dtb and static_test_2.dtb. If fdtoverlay detects an
|
|
# error than the kernel build will fail. static_test_1.dtb and
