[PATCH 4.19 136/287] mmc: cavium-octeon: Add of_node_put() when breaking out of loop

[Greg Kroah-Hartman]

From: Liang He <windhl@xxxxxxx>

[ Upstream commit 19bbb49acf8d7a03cb83e05624363741a4c3ec6f ]

In octeon_mmc_probe(), we should call of_node_put() when breaking
out of for_each_child_of_node() which has increased and decreased
the refcount during each iteration.
