Subject: [PATCH 0/2] Fix double counting of S/W ECC engines' ECC stat

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.
