dmaengine: edma: fixed wrongly initialized data parameter to the edma callback
The "data" parameter passed indirectly to the edma_callback() should be edma_chan and not the dma_chan. This bug was so far harmless since the offset of struct dma_chan within struct edma_chan is 0. However as soon as someone changes struct edma_chan this would cause troubles.
