ARM: 8427/1: dma-mapping: add support for offset parameter in dma_mmap()
commit 7e312103 upstream. IOMMU-based dma_mmap() implementation lacked proper support for offset parameter used in mmap call (it always assumed that mapping starts from offset zero). This patch adds support for offset parameter to IOMMU-based implementation.
