4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Qi Hou <qi.hou@windriver.com>
commit 2e1e4949f9dfb053122785cd73540bb1e61f768b upstream.
Refcount of of_node is increased with of_node_get() in i2c_mux_add_adapter().
It must be decreased with of_node_put() in i2c_mux_del_adapters().
