Subject: [PATCH] soc: samsung: exynos-pmu: select CONFIG_MFD_CORE
Date: Mon, 20 Sep 2021 12:06:08 +0200	[thread overview]
Message-ID: <20210920100613.1613919-1-arnd@kernel.org> (raw)
Message-ID: <20210920100608.4hFeOueXXt8NDJ-XlvTeg72Zv9JS-n8qqfu2KQmHmK8@z> (raw)

From: Arnd Bergmann <arnd@arndb.de>

Using devm_mfd_add_devices() fails if no driver selects the
MFD core code:

aarch64-linux-ld: drivers/soc/samsung/exynos-pmu.o: in function `exynos_pmu_probe':
exynos-pmu.c:(.text+0xa0): undefined reference to `devm_mfd_add_devices'

Add the missing select statement.

Fixes: 93618e344a5e ("soc: samsung: exynos-pmu: instantiate clkout driver as MFD")
