From 5bb9dbb5ae0931fa3c6780a45f651755266f9b6d Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Sun, 3 Jul 2016 00:00:55 +0530 Subject: [PATCH] dmaengine: imx-sdma: explicitly freeup irq dmaengine device should explicitly call devm_free_irq() when using devm_request_irq(). The irq is still ON when devices remove is executed and irq should be quiesced before remove is completed.
