commit 99974aedbd73523969afb09f33c6e3047cd0ddae upstream.
dma_async_device_register() can return non-zero error code. Add
condition to check the return value of dma_async_device_register
function and handle the error path.
Addresses-Coverity: Event check_return.
Fixes: 9cd4360de609 ("dma: Add Xilinx AXI Video Direct Memory Access Engine
driver support")
