From 95140ed16db560ef86ab4ebe1a4e9b748d098669 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 31 Jul 2017 10:55:00 +0200 Subject: [PATCH] psci: add CPU_IDLE dependency I ran into a build error for the psci_checker: drivers/firmware/psci_checker.o: In function `psci_checker': psci_checker.c:(.init.text+0x528): undefined reference to `cpuidle_devices' As far as I can tell, this is simply a very rare combination of options, but the problem has existed since the code was initially added. Adding a Kconfig dependency makes it build properly.
