[MTD] NAND: Fix breakage all over the place
Following problems are addressed: - wrong status caused early break out of nand_wait() - removed the bogus status check in nand_wait() which is a relict of the abandoned support for interrupted erase. - status check moved to the correct place in read_oob - oob support for syndrom based ecc with strange layouts - use given offset in the AUTOOOB based oob operations Partially based on a patch from Vitaly Vool <vwool@ru.mvista.com> Thanks to Savin Zlobec <savin@epico.si> for tracking down the status problem. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
