Subject: [PATCH v1 2/4] iommu/tegra: gart: Fix gart_iommu_unmap()
Date: Mon, 9 Apr 2018 23:07:20 +0300 [thread overview]
Message-ID: <dd25a9ff7bad7c92b345c0c0ce2bf235c4c3b6e8.1523304324.git.digetx@gmail.com> (raw)

In-Reply-To: <cover.1523304324.git.digetx-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
It must return the number of unmapped bytes on success, returning 0 means
that unmapping failed and in result only one page is unmapped.
