Subject: [PATCH] ARM: ux500: fix prcmu_is_cpu_in_wfi() calculation
Date: Wed, 16 Nov 2016 16:20:37 +0100 [thread overview]
Message-ID: <20161116152047.3336967-1-arnd@arndb.de> (raw)
This function clearly never worked and always returns true,
as pointed out by gcc-7:
arch/arm/mach-ux500/pm.c: In function 'prcmu_is_cpu_in_wfi':
arch/arm/mach-ux500/pm.c:137:212: error: ?: using integer constants in boolean context, the expression will always evaluate to 'true' [-Werror=int-in-bool-context]
With the added braces, the condition actually makes sense.
Fixes: 34fe6f107eab ("mfd : Check if the other db8500 core is in WFI")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
