4.17-stable review patch. If anyone has any objections, please let me know. ------------------ From: Nicholas Mc Guire <hofrat@xxxxxxxxx> [ Upstream commit 342639d996f18bc0a4db2f42a84230c0a966dc94 ] The call to of_get_next_child() returns a node pointer with refcount incremented thus it must be explicitly decremented here after the last usage.
