ARM: ux500: fix prcmu_is_cpu_in_wfi() calculation
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> Acked-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
