[ This is a fix specific to 4.4.y and 4.9.y stable trees; 4.14.y and older are not affected ]
The of-node refcount fixes were made in commit 8d1667200850 ("ASoC: qcom: Fix of-node refcount unbalance in apq8016_sbc_parse_of()"), but not enough in 4.4.y and 4.9.y. The modification of link->codec_of_node is missing. This fixes of-node refcount unbalance to link->codec_of_node.
