From e2d42311ffc9a5014eb129d02eb0e7bc791430f0 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Wed, 13 Jul 2016 10:13:08 +0800 Subject: [PATCH] iommu/arm-smmu: Drop devm_free_irq when driver detach There is no need to call devm_free_irq when driver detach. devres_release_all which is called after 'drv->remove' will release all managed resources.
