Subject: dmaengine: at_xdmac: fix to pass correct device identity to free_irq()
From: Wei Yongjun <weiyj.lk@xxxxxxxxx>
commit 6a8b0c6b18f62a277ffb2139d0c0253fe35d7feb upstream.
free_irq() expects the same device identity that was passed to
corresponding request_irq(), otherwise the IRQ is not freed.
