Subject: [PATCH v2 3/8] iommu/arm-smmu-v3: Remove boolean bitfield for 'ats_enabled' flag
Date: Wed, 21 Aug 2019 16:17:44 +0100 [thread overview]
Message-ID: <20190821151749.23743-4-will@kernel.org> (raw)
In-Reply-To: <20190821151749.23743-1-will@kernel.org>
There's really no need for this to be a bitfield, particularly as we
don't have bitwise addressing on arm64.
