From ac09281a026aad1fe489419bc948ba88b910e242 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 30 Apr 2012 13:18:53 +0000 Subject: ARM: at91: skip at91_io_desc definition for NOMMU On NOMMU systems, we do cannot remap the MMIO space, so the definition of at91_io_desc is unused. Without this patch, building at91x40_defconfig results in: arch/arm/mach-at91/setup.c:90:24: warning: 'at91_io_desc' defined but not used [-Wunused-variable] Signed-off-by: Arnd Bergmann Cc: Nicolas Ferre Cc: Jean-Christophe Plagniol-Villard --- arch/arm/mach-at91/setup.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/arm/mach-at91') diff --git a/arch/arm/mach-at91/setup.c b/arch/arm/mach-at91/setup.c index 944bffb08991..3a53f3dfca52 100644 --- a/arch/arm/mach-at91/setup.c +++ b/arch/arm/mach-at91/setup.c @@ -87,7 +87,7 @@ void __init at91_init_sram(int bank, unsigned long base, unsigned int length) iotable_init(desc, 1); } -static struct map_desc at91_io_desc __initdata = { +static struct map_desc at91_io_desc __initdata __maybe_unused = { .virtual = AT91_VA_BASE_SYS, .pfn = __phys_to_pfn(AT91_BASE_SYS), .length = SZ_16K, -- cgit v1.2.1
