[PATCH 4.19 106/287] i2c: mux-gpmux: Add of_node_put() when breaking out of loop

[Greg Kroah-Hartman]

From: Liang He <windhl@xxxxxxx>

[ Upstream commit 6435319c34704994e19b0767f6a4e6f37439867b ]

In i2c_mux_probe(), we should call of_node_put() when breaking out
of for_each_child_of_node() which will automatically increase and
decrease the refcount.
