The limitation to assign a link DMA channel for a BE iff the
corresponding host DMA channel is assigned to a connected FE is only
applicable if the PROCEN_FMT_QUIRK is set. So, remove it for platforms
that do not enable the quirk.

[1/1] ASoC: SOF: Intel: hda: Remove link assignment limitation
      commit: 2ce0d008dcc59f9c01f43277b9f9743af7b01dad

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
