From a85fc1b073406b3848661fcbb452497930dcc8af Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 22 Mar 2013 14:12:06 +0100 Subject: ASoC: atmel-pcm-dma: No need to wrap snd_dmaengine_pcm_close() If a PCM driver using the dmaengine PCM helper functions doesn't need to do anything special in its pcm_close callback, snd_dmaengine_pcm_close can be used directly for as the pcm_close callback and there is no need to wrap it in a custom function.
