[alsa-devel] [PATCH] ASoC: dwc: make pcm support built-in when necessary
The new PIO mode for the dwc audio driver causes a link failure when it is built as a loadable module but the audio driver is built-in:
sound/built-in.o: In function `i2s_irq_handler': :(.text+0x58c64): undefined reference to `dw_pcm_push_tx' sound/built-in.o: In function `dw_i2s_probe': :(.text+0x593dc): undefined reference to `dw_pcm_register'
We could link both into a single module, but apparently the author intended them to be separate, so this instead changes the Makefile to force the pcm module to be built-in if the base module is. This is a bit hacky but not as bad as trying to work around it in Kconfig language.

The patch
ASoC: dwc: make pcm support built-in when necessary
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
