[alsa-devel] [PATCH] ASoC: kirkwood: Fix erroneous double output while playing

[Jean-Francois Moine]

This patch fixes the setting of the register KIRKWOOD_PLAYCTL which did
always streaming on both I2S and SPDIF, ignoring the DAI ID.

The bug was introduced by the commit 75b9b65ee5a
 "ASoC: kirkwood: add S/PDIF support"
