- Subject: [PATCH 52/90] mtd: nand: add an mtd_to_nand() helper
- Some drivers are retrieving the nand_chip pointer using the container_of
- macro on a struct wrapping both the nand_chip and the mtd_info struct while
- the standard way of retrieving this pointer is through mtd->priv.
- Provide an helper to do that.
