[PATCH v2 0/2] ASoC: omap: sdma-pcm: modpost warning fix and include cleanup

[Peter Ujfalusi]

Hi,

Changes since v1:
- Changed the MODULE_LICENSE from "GPL" to "GPL v2" to match the SPDX line.

Since the sdma-pcm can be built as module it must have MODULE_LICENSE defined,
whcih I have missed:

After merging the sound-asoc tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

WARNING: modpost: missing MODULE_LICENSE() in sound/soc/omap/snd-soc-sdma.o
see include/linux/module.h for more information
WARNING: modpost: missing MODULE_LICENSE() in sound/soc/omap/snd-soc-sdma.o
see include/linux/module.h for more information

The first patch also going to fix runtime issue with module loading:
snd_soc_sdma: Unknown symbol devm_kmalloc (err 0)
snd_soc_sdma: Unknown symbol omap_dma_filter_fn (err 0)
snd_soc_sdma: Unknown symbol snd_dmaengine_pcm_prepare_slave_config (err 0)
snd_soc_sdma: Unknown symbol devm_snd_dmaengine_pcm_register (err 0)

As these symbols are EXPORT_SYMBOL_GPL()...

Introduced by commit

  dde637f2daf1 ("ASoC: omap: Introduce the generic_dmaengine_pcm based sdma-pcm")

The second patch is kust a small adjustement for the include files.

Regards,
Peter

Applied "ASoC: omap: sdma-pcm: Fix modpost warning" to the asoc tree

[Mark Brown]

The patch

   ASoC: omap: sdma-pcm: Fix modpost warning

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

[PATCH v2 2/2] ASoC: omap: sdma-pcm: Correction for the include files

[Peter Ujfalusi]

The sdma-pcm does not need any information from omap-dma.h, it only needs
to include the omap-dmaengine.h - for the omap_dma_filter_fn, but that
might not be needed at all as OMAP1 was converted to dma_slave_map, but
I can not test OMAP1.

Add the linux/device.h include as well for devm_kzalloc()
