Subject: soc: samsung: exynos-pmu: Fix compilation when nothing selects CONFIG_MFD_CORE
From: David Virag <virag.david003@xxxxxxxxx>
commit e37ef6dcdb1f4738b01cec7fb7be46af07816af9 upstream.
Commit 93618e344a5e ("soc: samsung: exynos-pmu: instantiate clkout
driver as MFD") adds a "devm_mfd_add_devices" call in the exynos-pmu
driver which depends on CONFIG_MFD_CORE. If no driver selects that
config, the build will fail if CONFIG_EXYNOS_PMU is enabled with the
following error:
drivers/soc/samsung/exynos-pmu.c:137: undefined reference to `devm_mfd_add_devices'
Fix this by making CONFIG_EXYNOS_PMU select CONFIG_MFD_CORE.
