From 486b10a255f70735585c90d334422da65dfe43ac Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Sun, 3 Jul 2016 00:02:29 +0530 Subject: [PATCH] dmaengine: k3dma: 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.
