Pankaj Dubey ce36f6ad86 ARM: EXYNOS: Fix potential NULL pointer access in exynos_sys_powerdown_conf 
If no platform devices binded to the driver but driver itself loaded and
exynos_sys_powerdown_conf is called from
arch/arm/mach-exynos/{suspend.c, pm.c} it will result in NULL pointer access,
to prevent this added check on pmu_context for NULL.
