mtd: nand: Only allocate ecc->{calc, code}_buf when actually needed
The only users of the ecc->{calc,code}_buf buffers are NAND controller drivers implementing ecc->calculate() and/or ecc->correct(). Since the ->oobsize can be non-negligle, especially on modern NAND devices, we'd better allocate it only when it is actually required. Make ecc->{calc,code}_buf allocation dependent on the presence of ecc->calculate() or ecc->correct(). Signed-off-by:Boris Brezillon <boris.brezillon@free-electrons.com> Reviewed-by:
