The "legacy" ECC layout used until 3.12-rc1 uses all the OOB area by computing the ECC strength and ECC step size ourselves. Commit 2febcdf8 ("mtd: gpmi: set the BCHs geometry with the ecc info") makes the driver use the ECC info (ECC strength and ECC step size) provided by the MTD code, and creates a different NAND ECC layout for the BCH, and use the new ECC layout. This causes a regression: We can not mount the ubifs which was created by the old NAND ECC layout. This patch fixes this issue by reverting to the legacy ECC layout. We will probably introduce a new device-tree property to indicate that the new ECC layout can be used. For now though, for the imminent 3.12 release, we just unconditionally revert to the 3.11 behaviour. This leaves a harmless cosmetic warning about an unused function. At this point in the cycle I really don't care. Signed-off-by:
