From: Arnd Bergmann <arnd@arndb.de>

The _hda_dsp_stream_put() function now depends on the
snd_hdac_ext_stream_release() interface from SND_HDA_EXT_CORE:

x86_64-linux-ld: vmlinux.o: in function `_hda_dsp_stream_put':
hda-stream.c:(.text+0xfac605): undefined reference to `snd_hdac_ext_stream_release'

Select this symbol the same way the other users do.

[1/1] ASoC: SOF: Intel: select CONFIG_SND_HDA_EXT_CORE from SND_SOC_SOF_HDA_COMMON
      commit: 3a7dbc729e42b95f1a82806a11128c1926ab26d8

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
