From aadfe4b5f17c172e1329db23c7eb4657dd4f44b6 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 22 Jan 2021 12:02:50 +0100 Subject: [PATCH] MIPS: jazz: always allow little-endian builds The kernel test robot keeps reporting the same bug when it shows up in new files after random unrelated patches: In file included from arch/mips/include/uapi/asm/byteorder.h:13, from arch/mips/include/asm/bitops.h:20, from include/linux/bitops.h:26, from include/linux/kernel.h:12, from include/linux/clk.h:13, from drivers/base/regmap/regmap-mmio.c:7: include/linux/byteorder/big_endian.h:8:2: warning: #warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN [-Wcpp] 8 | #warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN | ^~~~~~~ drivers/base/regmap/regmap-mmio.c: In function 'regmap_mmio_gen_context': >> drivers/base/regmap/regmap-mmio.c:274:2: error: duplicate case value 274 | case REGMAP_ENDIAN_NATIVE: | ^~~~ drivers/base/regmap/regmap-mmio.c:246:2: note: previously used here 246 | case REGMAP_ENDIAN_NATIVE: The problem is that some randconfig builds end up on the MIPS jazz platform with neither CONFIG_CPU_BIG_ENDIAN nor CONFIG_CPU_LITTLE_ENDIAN because no specific machine is selected. As it turns out, all jazz machines support little-endian kernels, so this can simply be allowed globally.
