The "DMA API usage improvement" patch will be needed later on when we will be about to add memory shrinker support to the driver, it also cleans up code nicely. Changelog: v7: - Factored out VirtIO fixes from [1] since I'll be working on the dma-buf locking in a separate patchset now. [1] https://lore.kernel.org/all/20220526235040.678984-1-dmitry.osipenko@collabora.com/ - Added r-b from Thomas Hellström. - Added more fixes-tags to the patches. - The part of the v6 "Correct drm_gem_shmem_get_sg_table() error handling" patch got merged into linux-next recent from another patch [2], but that patch missed to zero out shmem->pages on error. Hence I updated my patch to fix the merged fix.
