Message-Id: <1323760466-30333-1-git-send-email-pullip.cho@samsung.com> Date: Tue, 13 Dec 2011 16:14:26 +0900 From: KyongHo Cho <pullip.cho@...sung.com> To: linux-arm-kernel@...ts.infradead.org, linux-samsung-soc@...r.kernel.org, iommu@...ts.linux-foundation.org, linux-kernel@...r.kernel.org Cc: Joerg Roedel <joro@...tes.org>, Sanghyun Lee <sanghyun75.lee@...sung.com>, Kukjin Kim <kgene.kim@...sung.com>, Younglak Kim <younglak1004.kim@...sung.com>, KyongHo Cho <pullip.cho@...sung.com> Subject: [PATCH] iommu: Initialize domain->handler in iommu_domain_alloc() Since it is not guaranteed that an iommu driver initializes in its domain_init() function, it must be initialized with NULL to prevent calling a function in an arbitrary location when iommu fault occurred.
