    Date
    4.18-stable review patch.  If anyone has any objections, please let me know.

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

    From: Danny Smith <danny.smith@axis.com>

    [ Upstream commit 5ea752c6efdf5aa8a57aed816d453a8f479f1b0a ]

    Fixed range in safeload conditional to allow safeload to up to 20 bytes,
    without a lower limit.
