The virt_to_bus/bus_to_virt functions have been deprecated for as long as I can remember, and they are used in very few remaining instances, usually in obscure ISA device drivers. The OSS sound drivers are the only ones that are still used on the ARM architecture, and only on some of the earliest StrongARM machines. The problem for converting the OSS subsystem to use dma_map_single instead is that the caller of virt_to_bus does not have a device pointer, since the subsystem has never been ported to use the common device infrastructure.

The modular sound driver patches were funded by Red Hat Software (www.redhat.com). The sound driver here is thus a modified version of Hannu's code. Please bear that in mind when considering the appropriate forums for bug reporting. Alan Cox
