The patch
ASoC: ti: fix davinci_mcasp_probe dependencies
has been applied to the asoc tree at
https://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

The SND_SOC_DAVINCI_MCASP driver can use either edma or sdma as a back-end, and it takes the presence of the respective dma engine drivers in the configuration as an indication to which ones should be built. However, this is flawed in multiple ways:
- With CONFIG_TI_EDMA=m and CONFIG_SND_SOC_DAVINCI_MCASP=y, is enabled as =m, and we get a link error: sound/soc/ti/davinci-mcasp.o: In function `davinci_mcasp_probe': davinci-mcasp.c:(.text+0x930): undefined reference to `edma_pcm_platform_register'
- When CONFIG_SND_SOC_DAVINCI_MCASP=m has already been selected by another driver, the same link error appears even if CONFIG_TI_EDMA is disabled
There are possibly other issues here, but it seems that the only reasonable solution is to always build both SND_SOC_TI_EDMA_PCM and SND_SOC_TI_SDMA_PCM as a dependency here. Both are fairly small and do not have any other compile-time dependencies, so the cost is very small, and makes the configuration stage much more consistent.
