Use devm_ioremap_resource instead of reques_mem_region()/ioremap() and
devm_request_irq() instead of request_irq().
This ensures more consistent error values and simplifies error paths.

And you call that "more consistent error values"? Why not:
status = PTR_ERR(edmacc_regs_base[j]);
edma_cc[j] = kzalloc(sizeof(struct edma), GFP_KERNEL);
Maybe it's worth using devm_kzalloc() too?
