    Subject[ 11/59] mtd: sst25l: initialize writebufsize
    3.2-stable review patch.  If anyone has any objections, please let me know.


    From: Artem Bityutskiy <>

    commit c4cc625ea5958d065c21cc0fcea29e9ed8f3d2bc upstream.

    The writebufsize concept was introduce by commit
    "0e4ca7e mtd: add writebufsize field to mtd_info struct" and it represents
    the maximum amount of data the device writes to the media at a time. This is
    an important parameter for UBIFS which is used during recovery and which
    basically defines how big a corruption caused by a power cut can be.

    Set writebufsize to the flash page size because it is the maximum amount of
    data it writes at a time.
