Hello,
This series fix the double counting of S/W ECC engines' ECC stat
If you use SPI-NAND with SW-ECC engine, the ECC related statistics (ecc_stats.failed & ecc_stats.corrected) will be doubled, because those numbers will be double-counted in ecc-sw-[bch/hamming].c and drivers/mtd/nand/spi/core.c.
This can be found by using nandtest/nandbiterrs validation.
Thanks for your time.
