Subject[PATCH v3] mtd: spinand: read return badly if the last page has bitflips
Date
In case of the last page containing bitflips (ret > 0),
spinand_mtd_read() will return that number of bitflips for the last
page. But to me it looks like it should instead return max_bitflips like
it does when the last page read returns with 0.
