staging: gasket: fix mmap of coherent buffer when IOMMU translation on Coherent buffer mmap code assumes DMA addresses are physical addresses, which is patently wrong when a downstream IOMMU allocates and translates IOVAs for DMA mappings. Use dma_mmap_coherent(). Bug: 140076240 Bug: 111709861 Change-Id: Ieaa052378844aaf126ea3bc9dba544e7edb37bc7 Signed-off-by: Todd Poynor <toddpoynor@google.com>
