Wait, is 'name' actually ignored? It looks to me like it sets the MTD
name. See the comments in include/linux/spi/flash.h and
arch/arm/include/asm/mach/flash.h (BTW, why do we have two definitions
for this??):

  @name: optional flash device name (eg, as used with mtdparts=)

And I think it's used for exactly that in m25p80.c:

	if (data && data->name)
		flash->mtd.name = data->name;
