Subject: [PATCH 12/13] iommu/io-pgtable: Pass struct iommu_iotlb_gather to ->unmap()
Date: Wed, 14 Aug 2019 18:56:33 +0100	[thread overview]
Message-ID: <20190814175634.21081-13-will@kernel.org> (raw)
In-Reply-To: <20190814175634.21081-1-will@kernel.org>

Update the io-pgtable ->unmap() function to take an iommu_iotlb_gather
pointer as an argument, and update the callers as appropriate.
