From bb682f7a91af08f1fdb669d3911978d7166a65d1 Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Mon, 14 Feb 2022 11:14:04 +0100 Subject: ALSA: hda: Expose codec cleanup and power-save functions With few changes, snd_hda_codec_set_power_save() and snd_hda_codec_cleanup_for_unbind() can be re-used by ASoC drivers. While at it, provide kernel doc for the exposed functions.
