ASoC: dmaengine: Restore NULL prepare_slave_config() callback
commit 660564fc9a92a893a14f255be434f7ea0b967901 upstream.
As pointed out by Sascha Hauer, this patch changes:
if (pmc->config && !pcm->config->prepare_slave_config)
<do nothing>
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.
Fixes: 9a1e13440a4f ("ASoC: dmaengine: do not use a NULL prepare_slave_config() callback")
