dmaengine: k3dma: remove useless ON_WARN_ONCE()
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. Signed-off-by: Antonio Borneo <borneo.antonio@gmail.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
