Applied "ASoC: atmel-classd: select correct Kconfig symbol" to the asoc tree

[broonie@kernel.org (Mark Brown)]

The patch

   ASoC: atmel-classd: select correct Kconfig symbol

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

Subject: [PATCH] ASoC: atmel-classd: select correct Kconfig symbol

SND_ATMEL_SOC_CLASSD selects SND_ATMEL_SOC_DMA but the driver itself
handles its own DMA operations and doesn't need anything from
atmel-pcm-dma.c or atmel_ssc_dai.c.

Replace SND_ATMEL_SOC_DMA by SND_SOC_GENERIC_DMAENGINE_PCM which is the
only one actually required.

This may end up in a configuration leading to a link error:

sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio':
atmel_ssc_dai.c:(.text+0x79c): undefined reference to `atmel_pcm_dma_platform_register'
atmel_ssc_dai.c:(.text+0x79c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `atmel_pcm_dma_platform_register'
sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_put_audio':
atmel_ssc_dai.c:(.text+0xf24): undefined reference to `atmel_pcm_dma_platform_unregister'
atmel_ssc_dai.c:(.text+0xf24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `atmel_pcm_dma_platform_unregister'

Tested on sama5d2 xplained with the following configuration
where nothing selects SND_ATMEL_SOC_DMA:

CONFIG_SND_ATMEL_SOC=y
CONFIG_SND_ATMEL_SOC_CLASSD=y
