Subject: [PATCH 1/4] ASoC: hdac_hda: Disconnect struct hdac_hda_priv and hda_codec
Date: Wed, 20 Jul 2022 15:06:19 +0200	[thread overview]
Message-ID: <20220720130622.146973-2-cezary.rojewski@intel.com> (raw)
In-Reply-To: <20220720130622.146973-1-cezary.rojewski@intel.com>

Preliminary step in making snd_hda_codec_device_init() the only
constructor for struct hda_codec instances. To do that, no struct may
wrap struct hda_codec as its base type.

To drop hdac_to_hda_priv(), hdac_hda_dev_probe() now skips
dev_set_drvdata(). Driver private data will be assigned by owning bus
drivers instead.
