[alsa-devel] [PATCH 2/3] ASoC: topology: Align tplg pointer increment across all kcontrols

From: Liam Girdwood <liam.r.girdwood at linux.intel.com>

This aligns all kcontrol tplg pointer increments to be consistent
in the respective create methods and ensures that the position is
pointing to the next widget rather the current invalid widget.
