Subject[PATCH] cpuidle: tegra: add ARCH_SUSPEND_POSSIBLE dependency
Date
From: Arnd Bergmann <arnd@arndb.de>

Some StrongARM processors don't support suspend, which leads
to a build failure with the tegra cpuidle driver:

WARNING: unmet direct dependencies detected for ARM_CPU_SUSPEND
Depends on [n]: ARCH_SUSPEND_POSSIBLE [=n]
Selected by [y]:
- ARM_TEGRA_CPUIDLE [=y] && CPU_IDLE [=y] && (ARM [=y] || ARM64) && (ARCH_TEGRA [=n] || COMPILE_TEST [=y]) && !ARM64 && MMU [=y]

arch/arm/kernel/sleep.o: in function `__cpu_suspend':
(.text+0x68): undefined reference to `cpu_sa110_suspend_size'

Add an explicit dependency to make randconfig builds avoid
this combination.

Fixes: faae6c9f2e68 ("cpuidle: tegra: Enable compile testing")
