    Subject[PATCH 4.14 007/195] dmaengine: dmatest: fix container_of member in dmatest_callback
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Yang Shunyong <shunyong.yang@hxt-semitech.com>

    commit 66b3bd2356e0a1531c71a3dcf96944621e25c17c upstream.

    The type of arg passed to dmatest_callback is struct dmatest_done.
    It refers to test_done in struct dmatest_thread, not done_wait.

    Fixes: 6f6a23a213be ("dmaengine: dmatest: move callback wait ...")
