[PATCH 20/24] ASoC: dmaengine: Convert to generic PCM copy ops

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch converts the ASoC dmaenging driver code to use the new
unified PCM copy callback.  It's a straightforward conversion from
*_user() to *_sockptr() variants.

The process callback is still using the direct pointer as of now, but
it'll be converted in the next patch.
