    Subject[PATCH 4.7 120/143] crypto: qat - fix aes-xts key sizes
    Date
    4.7-stable review patch.  If anyone has any objections, please let me know.

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

    From: Giovanni Cabiddu <giovanni.cabiddu@intel.com>

    commit 10bb087ce381c812cd81a65ffd5e6f83e6399291 upstream.

    Increase value of supported key sizes for qat_aes_xts.
    aes-xts keys consists of keys of equal size concatenated.

    Fixes: def14bfaf30d ("crypto: qat - add support for ctr(aes) and xts(aes)")
