As pointed out by Sascha Hauer, this patch changes: if (pmc->config && !pcm->config->prepare_slave_config) to: if (pmc->config && !pcm->config->prepare_slave_config) snd_dmaengine_pcm_prepare_slave_config() This breaks the drivers that do not need a call to dmaengine_slave_config(). Drivers that still need to call snd_dmaengine_pcm_prepare_slave_config(), but have a NULL pcm->config->prepare_slave_config should use snd_dmaengine_pcm_prepare_slave_config() as their prepare_slave_config callback.
