| |
Building of EXYNOS5420_MCPM with disabled SUSPEND fails: arch/arm/mach-exynos/built-in.o: In function `exynos_mcpm_init': arch/arm/mach-exynos/mcpm-exynos.c:361: undefined reference to `mcpm_loopback'
The exynos_mcpm_init() in mcp-exynos.c calls mcpm_loopback() which depends on cpu_suspend function (ARM_CPU_SUSPEND).
