    Subject[PATCH 4.0 174/220] sd: Fix missing ATO tag check
    Date
    4.0-stable review patch.  If anyone has any objections, please let me know.

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

    From: "Martin K. Petersen" <martin.petersen@oracle.com>

    commit e557990e358934fb168d30371c9c0f63e314c6b8 upstream.

    3aec2f41a8bae introduced a merge error where we would end up check for
    sdkp instead of sdkp->ATO. Fix this so we register app tag capability
    correctly.
