[ Upstream commit 5d010473cdeaabf6a2d3a9e2aed2186c1b73c213 ]

Calling fwnode_get_next_child_node() in ACPI implementation of the fwnode property API is somewhat problematic as the latter is used in the impelementation of the former. Instead of using fwnode_get_next_child_node() in acpi_graph_get_next_endpoint(), call acpi_get_next_subnode() directly instead.
