Subject: [PATCH] drm/msm: use orig_nents to iterate over scatterlist with per-process tables
Date: Mon, 28 Mar 2022 08:55:05 -0400 [thread overview]
Message-ID: <20220328125505.31605-1-jonathan@marek.ca> (raw)
This matches the implementation of iommu_map_sgtable() used for the
non-per-process page tables path.
This works around the dma_map_sgtable() call (used to invalidate cache)
overwriting sgt->nents with 1 (which is probably a separate issue).
Fixes: b145c6e65eb0 ("drm/msm: Add support to create a local pagetable")
