4.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Yang Shunyong <shunyong.yang@xxxxxxxxxxxxxxxx> 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 ...")
