Subject: clk: ti: dra7-atl-clock: Fix of_node reference counting
From: Peter Ujfalusi <peter.ujfalusi@xxxxxx>
commit 660e1551939931657808d47838a3f443c0e83fd0 upstream.
of_find_node_by_name() will call of_node_put() on the node so we need to
get it first to avoid warnings.
The cfg_node needs to be put after we have finished processing the
properties.
