BTW, why doesn't the default hook in the core do like this?


static uint8_t nand_read_byte(struct mtd_info *mtd)
{
struct nand_chip *chip = mtd_to_nand(mtd);
uint8_t byte;

chip->read_buf(chip, &byte, 1);
return byte;
}


->read_byte() is a special case of ->read_buf() with length==1,
so this should work.
