Populate mtd->dev with flash_info->dev which allows to get full mtd information using the "mtd list" command. Before, "mtd list" command returns :
List of MTD devices: * nor0 - type: NOR flash - block size: 0x40000 bytes - min I/O: 0x1 bytes - 0x000000000000-0x000004000000 : "nor0"
After this patch we get for example:
List of MTD devices: * nor0 - device: flash@0 - parent: spi@40430000 - driver: cfi_flash - path: /soc/spi@40430000/flash@0 - type: NOR flash - block size: 0x40000 bytes - min I/O: 0x1 bytes - 0x000000000000-0x000004000000 : "nor0"
