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

Subject: [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.
