Subject: [PATCH] iommu: Initialize domain->handler in iommu_domain_alloc()
Date: Tue, 13 Dec 2011 16:14:26 +0900 [thread overview]
Message-ID: <1323760466-30333-1-git-send-email-pullip.cho@samsung.com> (raw)
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.
