Commit dfe64e2c89731a3f9950d7acd8681b68df2bae03:
mtd: resync with Linux-3.7.1
broke the docg4 driver. Specifically:
- some of the prototypes of the ecc methods changed
- the NAND_NO_AUTOINCR flag was removed
- the ecc.strength element was added.
This patch fixes these. Tested on the docg4 on my palmtre680 board.
