[alsa-devel] [PATCH 00/21] more arm build fixes
Hi subsystem maintainers,
Here is another set of patches that resulted from build testing on linux-next. Please apply directly into your trees if you agree, or let me know if I made a mistake.
I can take whatever remains through the arm-soc tree if you prefer that or I don't hear back.

ARM cannot handle udelay for more than 2 miliseconds, so we should use mdelay instead for those.

Thanks, applied to sound git tree.

-- 1.8.1.2
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.

Applied now, but the only problem is that it's difficult to test it :) Let's see.
Thanks!
