The patch

   ASoC: SOF: Intel: hda: move i915 init earlier

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Subject: [PATCH] ASoC: SOF: Intel: hda: move i915 init earlier

To be compliant with i915 display driver requirements, i915 power-up
must be done before any HDA communication takes place, including
parsing the bus capabilities. Otherwise the initial codec probe
may fail.

Move i915 initialization earlier in the SOF HDA sequence. This
sequence is now aligned with the snd-hda-intel driver where the
display_power() call is before snd_hdac_bus_parse_capabilities()
and rest of the capability parsing.

Also remove unnecessary ifdef around hda_codec_i915_init(). There's
a dummy implementation provided if CONFIG_SND_SOC_SOF_HDA is not
