[PATCH -next] dmaengine: at_xdmac: fix to pass correct device identity to free_irq()

[weiyj.lk@gmail.com (Wei Yongjun)]

free_irq() expects the same device identity that was passed to
corresponding request_irq(), otherwise the IRQ is not freed.

Fixes: e1f7c9eee707 ("dmaengine: at_xdmac: creation of the atmel
eXtended DMA Controller driver")
