Commit 36387a2b1f62b5c087c5fe6f0f7b23b94f722ad7 ("k3dma: Fix
memory handling in preparation for cyclic mode") adds few
calls to ON_WARN_ONCE() to track the use of ds_run/ds_done.After the two fixes: - dmaengine: k3dma: fix non-cyclic mode - dmaengine: k3dma: fix re-free of the same descriptor the behaviour of ds_run/ds_done is properly fixed. The remaining ON_WARN_ONCE() are never triggered and can be removed.
