    Subject[PATCH 4.14 06/67] mtd: nand: atmel: Fix get_sectorsize() function
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Boris Brezillon <boris.brezillon@bootlin.com>

    commit 2b1b1b4ac716fd929a2d221bd4ade62263bed915 upstream.

    get_sectorsize() was not using the appropriate macro to extract the
    ECC sector size from the config cache, which led to buggy ECC when
    using 1024 byte sectors.

    Fixes: f88fc122cc34 ("mtd: nand: Cleanup/rework the atmel_nand driver")
