    Subject[ 13/55] RDMA/cxgb4: Drop peer_abort when no endpoint found
    3.0-stable review patch.  If anyone has any objections, please let me know.

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

    From: Steve Wise <swise@opengridcomputing.com>

    commit 14b9222808bb8bfefc71f72bc0dbdcf3b2f0140f upstream.

    Log a warning and drop the abort message. Otherwise we will do a
    bogus wake_up() and crash.
