From 46cf94d6ab38420690d890d9922bfc61a7b3e2c5 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Tue, 5 Jul 2016 10:02:16 +0530 Subject: [PATCH] dmaengine: pl330: 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.
