Hello,
I tried today's linux-next on OMAP platform and audio is not probing because
dma_alloc_writecombine() fails to get the area.
My linux-next from two days ago works OK and I don't see anything directly
connected to OMAP which can cause this failure.
Can someone try linux-next on non OMAP platform to see if
dma_alloc_writecombine() works there?
Meanwhile I'll try to find the reason why it fails for me.
Thanks,
Péter

Do you have CMA enabled? There seems to be some breakage there for me
on Samsung platforms, I saw this affecting all DMA users yesterday along
with some other CMA related issues but didn't analyse it enough to
report it.

I do had CMA enabled (not sure why) It has been enabled in my config for a
long time.
Without CONFIG_CMA all is fine.
Thank you,
Péter
