Subject: [RESEND PATCH v2 0/6] ALSA: hda: Unify codec construction
Date: Tue, 16 Aug 2022 13:17:21 +0200	[thread overview]
Message-ID: <20220816111727.3218543-1-cezary.rojewski@intel.com> (raw)

A follow up to the recent HDAudio fixes series [1]. Given the recently
reported regression [2], before the page fault occurring on codec
shutdown can be fixed, codec construction procedure needs to be updated
for skylake and sof-intel drivers. Drivers: pci-hda and avs need no
changes - already making use of snd_hda_codec_device_init().

As subject touches code used by the sof-driver, additional review has
been conducted on thesofproject/linux [3].

Changes in v2:

- dropped snd_hda_ext_core <-> snd_hda_codec dependency by calling
  snd_hda_codec_device_init() directly in skylake and sof drivers probe
  enumeration routines, as suggested by Takashi
- skylake/sof portion of the change has been split into two separate
  patches

- new functions that aim to replace hdac_ext codec init & exit
  functionality are added first - for skylake and sof drivers both
- third patch in the series now combines the "field -> pointer" change
  for hdac_hda_priv->codec plus the codec-enumeration adjustments for
  skylake and sof drivers
  Both above are here to keep git bisect happy, as suggested by Pierre
