Subject: [PATCH 1/3] ASoC: ti: remove compat dma probing
Date:   Thu,  7 Mar 2019 16:16:08 +0100

After running into a link error:

sound/soc/ti/edma-pcm.o:(.rodata+0x18): undefined reference to `edma_filter_fn'

I checked all users of this, and they have new-style 'dma_slave_map' tables,
so none of them should still need it. Removing the associated lines
simplifies the code and avoids the build-time dependency on the
respective dmaengine drivers.

v2: remove header inclusions as well

I added the two dmaengine patches to the series this time, but
we probably want to have those merged separately through the
dmaengine tree, while this one should get merged as a bugfix
through ASoC.
