ARM: ux500: fix prcmu_is_cpu_in_wfi() calculation
commit f0e8faa7a5e894b0fc99d24be1b18685a92ea466 upstream.
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")
