From f0e8faa7a5e894b0fc99d24be1b18685a92ea466 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 16 Nov 2016 16:20:37 +0100 Subject: [PATCH] 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.
