The warning has been there for quite some time, finally got around to report it. CC [M] drivers/media/video/video-buf.o drivers/media/video/video-buf.c: In function `videobuf_iolock': drivers/media/video/video-buf.c:327: warning: cast from pointer to integer of different size The specific code is /* FIXME: need sanity checks for vb->boff */ bus = (dma_addr_t)fbuf->base + vb->boff; bus is dma_addr_t (==u32 on sparc64), base is void* So if buf->base is really an arbitrary pointer, it might not fit into u32. What is it actually? -- Meelis Roos (mroos@linux.ee)
