The hda-sdw-bpt code links against the soundwire driver, but that fails when
trying to link from built-in code into loadable module:

x86_64-linux-ld: vmlinux.o: in function `intel_ace2x_bpt_close_stream.isra.0':
intel_ace2x.c:(.text+0x137a531): undefined reference to `hda_sdw_bpt_close'
x86_64-linux-ld: vmlinux.o: in function `intel_ace2x_bpt_send_async':
intel_ace2x.c:(.text+0x137aa45): undefined reference to `hda_sdw_bpt_open'
x86_64-linux-ld: intel_ace2x.c:(.text+0x137ab67): undefined reference to `hda_sdw_bpt_close'
x86_64-linux-ld: intel_ace2x.c:(.text+0x137ac30): undefined reference to `hda_sdw_bpt_send_async'
x86_64-linux-ld: vmlinux.o: in function `intel_ace2x_bpt_wait':
intel_ace2x.c:(.text+0x137aced): undefined reference to `hda_sdw_bpt_wait'

Ensure that both SOUNDWIRE_INTEL and SND_SOF_SOF_HDA_SDW_BPT are selected
at the same time by SND_SOC_SOF_INTEL_LNL, and that this happens even if
SND_SOC_SOF_INTEL_SOUNDWIRE is a loadable module but SND_SOC_SOF_INTEL_LNL
is built-in.

This follows the same logic as commit c5a61db9bf89 ("ASoC: SOF: fix
intel-soundwire link failure").

Thanks!

[1/1] ASoC: SOF: Intel: hda-sdw-bpt: fix SND_SOF_SOF_HDA_SDW_BPT dependencies
      commit: 614d416dd8aee2675fb591c598308a901a660db8

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
