[PATCH v2 21/23] mtd: rawnand: Pass a nand_chip object to chip->setup_data_interface()
Boris Brezillon

Thu Sep 6 12:05:33 UTC 2018
Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->setup_data_interface() hook.
