ARM: EXYNOS: Fix double of_node_put() when parsing child power domains
On each next iteration of for_each_compatible_node() the reference counter for current device node is already decreased by the loop iterator. The manual call to of_node_get() is required only on loop break which is not happening here. The double of_node_get() (with enabled CONFIG_OF_DYNAMIC) lead to decreasing the counter below expected, initial value. Fixes: fe4034a3fad7 ("ARM: EXYNOS: Add missing of_node_put() when parsing power domains") Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Cc: <stable@vger.kernel.org> Signed-off-by: Kukjin Kim <kgene@kernel.org>
