From 91457df7733564015f846c501424610318a5b85f Mon Sep 17 00:00:00 2001 From: Cyril Roelandt Date: Tue, 12 Feb 2013 05:01:50 +0100 Subject: [PATCH] iommu/amd: Remove redundant NULL check before dma_ops_domain_free(). dma_ops_domain_free on a NULL pointer is a no-op, so the NULL check in amd_iommu_init_dma_ops() can be removed.
