[PATCH 0/2] ASoC: SOF: Remove unused members from struct sof_dev_desc

[PATCH 0/2] ASoC: SOF: Remove unused members from struct sof_dev_desc

[Peter Ujfalusi]

Hi,

dma_engine, dma_size and resindex_dma_base is unused from sof_dev_desc, drop
them.

resindex_dma_base is initialized to -1 for Intel platforms, but it is not used.

Regards,
Peter

[PATCH 1/2] ASoC: SOF: intel: Do no initialize resindex_dma_base

[Peter Ujfalusi]

.resindex_dma_base is not used by the code and in all instances it is set
to -1.
To make it possible to remove it from the sof_dev_desc struct, first remove
all references from the intel drivers (initialization).

[PATCH 2/2] ASoC: SOF: Drop resindex_dma_base, dma_engine, dma_size from sof_dev_desc

[Peter Ujfalusi]

resindex_dma_base, dma_engine and dma_size is unused, remove them.
There is no hint in the comments how this supposed to be used, when the
need arises it can be added back.

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
