Subject: [RESEND PATCH v2 1/6] ASoC: Intel: Skylake: Introduce HDA codec init and exit routines
Date: Tue, 16 Aug 2022 13:17:22 +0200	[thread overview]
Message-ID: <20220816111727.3218543-2-cezary.rojewski@intel.com> (raw)
In-Reply-To: <20220816111727.3218543-1-cezary.rojewski@intel.com>

Preliminary step in making snd_hda_codec_device_init() the only
constructor for struct hda_codec instances. To do that, existing usage
of hdac_ext equivalents has to be dropped.
