[PATCH 4.14 007/195] dmaengine: dmatest: fix container_of member in dmatest_callback

From: Greg Kroah-Hartman
Date: Thu Feb 15 2018 - 12:44:37 EST


4.14-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 ...")
