[alsa-devel] Applied "ASoC: SOF: Intel: hda: use SOF defined init chip in resume" to the asoc tree

[Mark Brown]

The patch

   ASoC: SOF: Intel: hda: use SOF defined init chip in resume

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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.

Thanks,
Mark

Subject: [PATCH] ASoC: SOF: Intel: hda: use SOF defined init chip in resume

Unify resume code by using SOF common function hda_dsp_ctrl_init_chip()
which can handle both HDA and non-HDA cases. Move code to reset
stream-to-link mapping into hda_dsp_ctrl_init_chip().
