Subject: [PATCH 2/2] ARM: imx: select ARM_CPU_SUSPEND for CPU_IDLE as well
Date: Thu, 15 Mar 2018 16:13:19 +0100	[thread overview]
Message-ID: <20180315151345.3089601-2-arnd@arndb.de> (raw)
In-Reply-To: <20180315151345.3089601-1-arnd@arndb.de>

The cpuidle support calls cpu_suspend(), which is compiled conditionally,
and fails to link unless something selects CONFIG_ARM_CPU_SUSPEND.

arch/arm/mach-imx/cpuidle-imx6sx.o: In function `imx6sx_enter_wait':
cpuidle-imx6sx.c:(.text+0x6c): undefined reference to `cpu_suspend'

This adds an explicit select statement here.
