[PATCH AUTOSEL 4.4 20/30] ARM: exynos: Clear global variable on init error path

From: Krzysztof Kozlowski [ Upstream commit cd4806911cee3901bc2b5eb95603cf1958720b57 ] For most of Exynos SoCs, Power Management Unit (PMU) address space is mapped into global variable 'pmu_base_addr' very early when initializing PMU interrupt controller. A lot of other machine code depends on
