Following patches contain minor changes, cleaning up code to be easier to read. Clean up few loops, to be simpler or altogether remove them. Rename some things to make code easier to understand.

Amadeusz Sławiński (6): ASoC: topology: Use for loop instead of while ASoC: topology: Remove unnecessary looping ASoC: topology: Return bool instead of int ASoC: topology: Rename SOC_TPLG_PASS_MIXER to _CONTROL ASoC: topology: Correct error message ASoC: topology: Rename soc_tplg_init_kcontrol() function

New subject: [PATCH 1/6] ASoC: topology: Use for loop instead of while

The 'while' loop can be replaced with a 'for' loop, making it more clear about what possible values there are, by having all of it in one place, instead of scattered around.

New subject: [PATCH 2/6] ASoC: topology: Remove unnecessary looping

Functions creating kcontrols as written allow for creation of multiple kcontrols at the same time, but in practice they are called for each kcontrol individually. Remove unnecessary loop as code always loops once anyway. This reduces intendation level allowing for some code to be put on one line instead of multiple lines.

In practice soc_tplg_is_eof() returns boolean value and caller uses the return value in such way, so convert the function to really do it.

Name of SOC_TPLG_PASS_MIXER pass is bit confusing, suggesting that it may only apply to mixers. As it is used for all control types, change name to SOC_TPLG_PASS_CONTROL.

New subject: [PATCH 5/6] ASoC: topology: Correct error message

Error message refers to mixer, but it is used for various other types of controls, so change it to refer to generic "controls".

New subject: [PATCH 6/6] ASoC: topology: Rename soc_tplg_init_kcontrol() function

Other functions used for callbacks are named after function they call, however function calling control_load seems to be an exception. Rename it to soc_tplg_control_load().

While avs-driver is not fully upstreamed yet, I believe it is still vital to state that patches have been tested on following cAVS 1.5 platforms i.e.: Skylake, Kabylake, Amberlake, Appololake and their variants with the avs-drivers.

As code looks good to me:

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
