The patch

   ASoC: SOF: ipc: introduce no_stream_position in sof_ipc_stream_params struct

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

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: ipc: introduce no_stream_position in
 sof_ipc_stream_params struct

The host period bytes value needs to be passed to firmware.
However current implementation uses this field for different
purpose - to indicate whether FW should send stream position
to the host. Therefore this patch introduces another field
"no_stream_position", a boolean value aimed to store information
about position tracking. This way host_period_bytes preserves its
original value.
