+Subject: ASoC: fsl: Fix of-node refcount unbalance in fsl_ssi_probe_from_dt()
+
+From: Takashi Iwai <tiwai@suse.de>
+
+commit 2757970f6d0d0a112247600b23d38c0c728ceeb3 upstream.
+
+The node obtained from of_find_node_by_path() has to be unreferenced
+after the use, but we forgot it for the root node.
+
+Fixes: f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support")
