cec4fa75 ("drm/omap: use refcount API to track the number of users of dma_addr") changed omap_gem.c to use refcounting API to track dma_addr uses. However, the driver only tracks the refcounts for non-contiguous buffers, and the patch didn't fully take this in account. After the patch, the driver always decreased refcount in omap_gem_unpin, instead of decreasing the refcount only for non-contiguous buffers. This leads to refcounting mismatch. As for the contiguous cases the refcount is never increased, fix this issue by returning from omap_gem_unpin if the buffer being unpinned is contiguous. Signed-off-by:

All the display related blocks on Tegra require contiguous memory. Using the DMA API, there is no knowing at import time which device will end up using the buffer, so it's not known whether or not an IOMMU will be used to map the buffer. Move the check for non-contiguous buffers/mappings to the tegra_dc_pin() function which is now the earliest point where it is known if a DMA BUF can be used by the given device or not. v2: add check for contiguous buffer/mapping in tegra_dc_pin() Reviewed-by:

Buffers that are imported from a DMA-BUF don't have pages allocated with them. At the same time an SG table for them can't be derived using the DMA API helpers because the necessary information doesn't exist. However there's already an SG table that was created during import, so this can simply be duplicated. Signed-off-by: -
