Hi Mark

We have soc-component.c now, but still many component related functions are implemented many place. This patch-set collect these into soc-component.c.

v1 -> v2 - remove soc-compress.c exchange (But I have plan to repost it) - fixup loop break issue on some functions - direct return on some functions

New subject: [PATCH v2 01/12] ASoC: soc-component: add soc_component_pin() and share code

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

soc-component has too many snd_soc_component_xxx_pin_xxx() functions. The difference between these functions are used function name and enable/disable. This patch adds common soc_component_pin() and share code.

New subject: [PATCH v2 10/12] ASoC: soc-component: merge soc-io.c into soc-component.c

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

soc-io.c has snd_soc_component_xxx() functions for I/O. We have soc-componennt.c for it. Let's merge soc-io.c into soc-component.c

By this patch, original soc-io.c functions start to use soc_component_err() when error case.

Hi Mark

We have soc-component.c now, but still many component related functions are implemented many place. This patch-set collect these into soc-component.c.

v1 -> v2

remove soc-compress.c exchange (But I have plan to repost it)

fixup loop break issue on some functions

direct return on some functions

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
