Subject: [PATCH] ARM: exynos: add missing of_node_put for loop iteration
Date: Sun, 25 Apr 2021 19:49:45 +0200	[thread overview]
Message-ID: <20210425174945.164612-1-krzysztof.kozlowski@canonical.com> (raw)

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")
Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>
