[alsa-devel] [PATCH] ASoC: qcom: move clock names into LPASS variant struct
The clock names for the two supported codecs are either "mi2s-*" name variants generated by code. This naming scheme does not work for platforms like MSM8660 which has I2S channels named CODEC_I2S_SPKR (rather than just "MI2S tertiary" and other repetitive names) and consequently have clocks named "codec-i2s-spkr-osr-clk" and similar.
Skip the runtime generation of clock names and replace it with name lookup tables encoded into the variant data.

The patch
ASoC: qcom: move clock names into LPASS variant struct
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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
