- Subject: [PATCH 02/15] mtd: nand: Add a new helper to retrieve the ECC context
- Introduce nand_to_ecc_ctx() which will allow to easily jump to the
- private pointer of an ECC context given a NAND device. This is very
- handy, from the prepare or finish ECC hook, to get the internal context
- out of the NAND device object.
