The commit 6b41030fdc79 ("dmaengine: dmatest: Restore default for channel") broke my use case when I tried to start busy channel. So, before this patch ... echo "busy_chan" > channel echo 1 > run sh: write error: Device or resource busy [ 1013.868313] dmatest: Could not start test, no channels configured After I have got it run on *ALL* available channels. dmatest compiled as a module. Fix this ASAP, otherwise I will send revert of this and followed up patch next week. -- With Best Regards, Andy Shevchenko
