Subject: [PATCH] ASoC: ti: Fix SDMA users not providing channel names
commit 3e802e90ffcce333127d928eaefdfcc34af233e8 upstream.
McBSP used to work correctly as long as compat DMA probing, removed by
commit 642aafea8889 ("ASoC: ti: remove compat dma probing"), was
available. New method of DMA probing apparently requires users to
provide channel names when registering with SDMA, while McBSP passes
NULLs. Fix it.
The same probably applies to McASP (not tested), hence the patch fixes
Fixes: 642aafea8889 ("ASoC: ti: remove compat dma probing")
