Subject: [PATCH] mtd: spinand: Fill a default ECC provider/algorithm
The SPI-NAND layer default is on-die ECC because until now it was the
only one supported. New SPI-NAND chip flavors might use something else
as ECC engine provider but this will always be the default if the user
does not choose explicitly something else.
