From 144fa37f5b4f9b81dfab79c8d440b4aba8b07fde Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Mon, 4 Jul 2016 15:41:25 +0530 Subject: [PATCH] dmaengine: moxart-dma: 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.
