[alsa-devel] [PATCH 14/21] ASoC: SOF: Intel: hda: use SOF defined init chip in resume

[Pierre-Louis Bossart]

From: Zhu Yingjiang <yingjiang.zhu at linux.intel.com>

Unify resume code by using SOF common function hda_dsp_ctrl_init_chip()
which can handle both HDA and non-HDA cases. Move code to reset
stream-to-link mapping into hda_dsp_ctrl_init_chip().
