mtd: nand: Change dependency between the NAND and ECC cores
The NAND ECC core is included in the generic NAND core when it is compiled in. Different software ECC engines drivers will select the NAND ECC core and thus also have a dependency on the NAND core. Using a "depends on" between the two leads to possible cases (not real cases, but created by robots) where one is still unselected because of the "select does not verifies depends on" game: WARNING: unmet direct dependencies detected for MTD_NAND_ECC Depends on [n]: MTD [=m] && MTD_NAND_CORE [=n] Selected by [m]: - MTD_NAND_ECC_SW_HAMMING [=y] && MTD [=m] - MTD_NAND_ECC_SW_BCH [=y] && MTD [=m] Fix this by using a select instead.
