commit 5d009e024056ded20c5bb1583146b833b23bbd5a upstream.
__of_get_dma_parent() returns OF device node @args.np, but the node's
refcount is increased twice, by both of_parse_phandle_with_args() and
of_node_get(), so causes refcount leakage for the node.
Fix by directly returning the node got by of_parse_phandle_with_args().
Fixes: f83a6e5dea6c ("of: address: Add support for the parent DMA bus")
