[alsa-devel] [PATCH 1/2] ASoC: soc-generic-dmaengine-pcm: Fix error handling

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at nxp.com>

When dmaengine_pcm_request_chan_of() fails it should release
the previously acquired resources, which in this case is to
call kfree(pcm), so jump to the correct point in the error
path.
