[PATCH 2/2] ARM: imx: select ARM_CPU_SUSPEND for CPU_IDLE as well
From: Arnd Bergmann
Date: Thu Mar 15 2018 - 11:16:45 EST
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.
