rbd: work around -Wuninitialized warning
gcc -O3 warns about a dummy variable that is passed down into rbd_img_fill_nodata without being initialized: drivers/block/rbd.c: In function 'rbd_img_fill_nodata': drivers/block/rbd.c:2573:13: error: 'dummy' is used uninitialized in this function [-Werror=uninitialized] fctx->iter = *fctx->pos; Since this is a dummy, I assume the warning is harmless, but it's better to initialize it anyway and avoid the warning. Fixes: mmtom ("init/Kconfig: enable -O3 for all arches") Signed-off-by: Arnd Bergmann <arnd@arndb.de> Reviewed-by: Ilya Dryomov <idryomov@gmail.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
