From b316d02a13c3a8ebe681b7232defbdf3fa28c41b Mon Sep 17 00:00:00 2001 From: Peter Xu Date: Mon, 22 May 2017 18:28:51 +0800 Subject: iommu/vt-d: Unwrap __get_valid_domain_for_dev() We do find_domain() in __get_valid_domain_for_dev(), while we do the same thing in get_valid_domain_for_dev(). No need to do it twice.
