Subject[RESEND PATCH v2 3/3] ARM: EXYNOS: Add missing of_node_put() when parsing power domains
Date
From: Krzysztof Kozlowski <k.kozlowski@samsung.com>

Add missing of_node_put() to:
1. Error return path if allocating memory for exynos_pm_domain failed.
2. Second iteration over power domains if a child domain was not present
or was incomplete.

Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>
Reported-by: Karol Wrona <k.wrona@samsung.com>
