[PATCHv8 03/26] v4l: vb2: add support for shared buffer (dma_buf)

From: Sumit Semwal This patch adds support for DMABUF memory type in videobuf2. It calls relevant APIs of dma_buf for v4l reqbuf / qbuf / dqbuf operations. For this version, the support is for videobuf2 as a user of the shared buffer; so the allocation of the buffer is done
