Most are caused by pointers marked as __iomem when they aren't or not marked as __iomem when they should. Also note that readl/writel already do endian conversion, so there is no need to do it again. saa7164_bus_set/get were a bit tricky: you have to make sure the msg endian conversion is done at the right time, and that the code isn't using fields that are still little endian instead of cpu-endianness. The approach chosen is to convert just before writing to the ring buffer and to convert it back right after reading from the ring buffer.
