From 6a8b0c6b18f62a277ffb2139d0c0253fe35d7feb Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 10 Aug 2016 03:17:09 +0000 Subject: [PATCH] dmaengine: at_xdmac: fix to pass correct device identity to free_irq() free_irq() expects the same device identity that was passed to corresponding request_irq(), otherwise the IRQ is not freed.
