Subject[PATCH 5.4 117/149] ARM: exynos: add missing of_node_put for loop iteration
Date
From: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>

[ Upstream commit 48d551bf20858240f38a0276be3016ff379918ac ]

Early exits from for_each_compatible_node() should decrement the
node reference counter. Reported by Coccinelle:

arch/arm/mach-exynos/exynos.c:52:1-25: WARNING:
Function "for_each_compatible_node" should have of_node_put() before break around line 58.

Fixes: b3205dea8fbf ("ARM: EXYNOS: Map SYSRAM through generic DT bindings")
