Marking the local variable as uninitialized_var shuts up that warning. Without this patch, building acs5k_defconfig results in: drivers/mtd/chips/cfi_cmdset_0002.c: In function 'cfi_amdstd_panic_write': include/linux/mtd/map.h:331:11: warning: 'r.x[0]' may be used uninitialized in this function [-Wuninitialized] drivers/mtd/chips/cfi_cmdset_0002.c: In function 'cfi_amdstd_write_words': include/linux/mtd/map.h:331:11: warning: 'r.x[0]' may be used uninitialized in this function [-Wuninitialized] drivers/mtd/chips/cfi_cmdset_0001.c: In function 'cfi_intelext_write_words': include/linux/mtd/map.h:331:11: warning: 'r.x[0]' may be used uninitialized in this function [-Wuninitialized] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com> 2012-11-15T17:50:30+00:00 Viresh Kumar viresh.kumar@linaro.org 2012-10-29T17:17:26+00:00 urn:sha1:3e9ce49e0ef95e22790a74720f0068696b2477c9 This patch is an attempt to fix following compilation warning.

So there is a chance that it might be passed uninitialized. Better initialize to zero.

(2) asm/cmpxchg.h Moved xchg() and cmpxchg() here. #included in asm/atomic.h. (3) asm/bug.h Moved die() and similar here. (4) asm/exec.h Moved arch_align_stack() here.

The globally defined CFI endianness (CONFIG_MTD_CFI_NOSWAP, CONFIG_MTD_CFI_BE_BYTE_SWAP or CONFIG_MTD_CFI_LE_BYTE_SWAP) becomes the default value which can be overridden by a driver for a particular device.
