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")

I've already tagged the pull requests for 5.13, so I guess you can
just add this into
your next fixes branch.
