From 76381c245b016cf200f35f914e5de7ad087d3e38 Mon Sep 17 00:00:00 2001 From: Zhu Yingjiang Date: Mon, 27 May 2019 16:40:59 +0800 Subject: [PATCH 1/3] ASoC: SOF: Intel: hda: set position buffer in init chip Set the HDA stream position buffer during init chip. The position buffer needs to be set in both HDA codec and nocodec cases. Using SOF defined function and move it to common code.
