    Subject[PATCH 4.19 60/64] mtd: spinand: Explicitly use MTD_OPS_RAW to write the bad block marker to OOB
    Date
    From: Frieder Schrempf <frieder.schrempf@kontron.de>

    commit 621a7b780bd8b7054647d53d5071961f2c9e0873 upstream.

    When writing the bad block marker to the OOB area the access mode
    should be set to MTD_OPS_RAW as it is done for reading the marker.
    Currently this only works because req.mode is initialized to
    MTD_OPS_PLACE_OOB (0) and spinand_write_to_cache_op() checks for
    req.mode != MTD_OPS_AUTO_OOB.

    Fix this by explicitly setting req.mode to MTD_OPS_RAW.
