The comment for ecc.read_page() requires that it should return "0 if bitflips uncorrectable". Actually, drivers could return positive values when uncorrectable bitflips occur. For example, nand_read_page_swecc() is the case. If ecc.correct() returns -EBADMSG for the first ECC sector, and a positive value for the second one, nand_read_page_swecc() returns a positive max_bitflips and increments ecc_stats.failed for the same page. The requirement can be relaxed by tweaking nand_do_read_ops(). Move the max_bitflips calculation below the retry.
