Subject: [PATCH 03/11] iommu: Use Functions to set default domain type in iommu_set_def_domain_type()
Date: Mon, 19 Aug 2019 15:22:48 +0200 [thread overview]
Message-ID: <20190819132256.14436-4-joro@8bytes.org> (raw)
In-Reply-To: <20190819132256.14436-1-joro@8bytes.org>
From: Joerg Roedel <jroedel@suse.de>
There are functions now to set the default domain type which
take care of updating other necessary state. Don't open-code
it in iommu_set_def_domain_type() and use those functions
instead.
