of: overlay: do not duplicate properties from overlay for new nodes
commit 8814dc46bd9e347d4de55ec5bf8f16ea54470499 upstream. When allocating a new node, add_changeset_node() was duplicating the properties from the respective node in the overlay instead of allocating a node with no properties. When this patch is applied the errors reported by the devictree unittest from patch "of: overlay: add tests to validate kfrees from overlay removal" will no longer occur. These error messages are of the form: "OF: ERROR: ..." and the unittest results will change from: ### dt-test ### end of unittest - 203 passed, 7 failed to ### dt-test ### end of unittest - 210 passed, 0 failed Tested-by: NAlan Tull <atull@kernel.org> Signed-off-by: NFrank Rowand <frank.rowand@sony.com> Cc: Guenter Roeck <linux@roeck-us.net> Signed-off-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org>
