Subject: [PATCH] psci: add CPU_IDLE dependency
Date: Mon, 31 Jul 2017 10:55:00 +0200 [thread overview]
Message-ID: <20170731085523.320244-1-arnd@arndb.de> (raw)
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.
Fixes: ea8b1c4a6019 ("drivers: psci: PSCI checker module")

Run the PSCI checker during startup. This checks that hotplug and
suspend operations work correctly when using PSCI.
