mtd: rawnand: Allow controllers to overload soft ECC hooks (0e7f4b64) · Commits · 戴 / test

Some controller drivers do not support executing regular nand_read/write_page_raw() helpers. For that, we created nand_monolithic_read/write_page_raw() alternatives. Let's now allow the driver to overload the ECC ->read/write_page_raw() hooks. Signed-off-by:
