Bo Shen e011143454 ASoC: atmel: disable error interrupt
As once the error interrupt is triggered, it can not be cleared.
So, disable it.

No side effect found while testing on sama5d3xek and at91sam9x5ek
boards.

Nicolas Ferre fdbcb3cba5 ASoC: atmel: machine driver for at91sam9x5-wm8731 boards
Description of the Asoc machine driver for an at91sam9x5 based board
with a wm8731 audio DAC. Wm8731 is clocked by a crystal and used as a
master on the SSC/I2S interface. Its connections are a headphone jack
and an Line input jack.

[Richard: this is based on an old patch from Nicolas that I forward
ported and reworked to use only device tree]

Lars-Peter Clausen 7c1c1d4a7b ASoC: dmaengine-pcm: Make requesting the DMA channel at PCM open optional
Refactor the dmaengine PCM library to allow the DMA channel to be requested
before opening a PCM substream. snd_dmaengine_pcm_open() now expects a DMA
channel instead of a filter function and filter parameter as its parameters.
snd_dmaengine_pcm_close() is updated to not release the DMA channel. This allows
a dmaengine based PCM driver to request its channels before the substream is
opened.

The patch also introduces two new functions, snd_dmaengine_pcm_open_request_chan()
and snd_dmaengine_pcm_close_release_chan(), which have the same signature and
behaviour of the old snd_dmaengine_pcm_{open,close}() and internally use the new
variants of these functions. All users of snd_dmaengine_pcm_{open,close}() are
updated to use snd_dmaengine_pcm_open_request_chan() and
snd_dmaengine_pcm_close_release_chan().

commit 739be96 "ASoC: Fix build dependency for SND_ATMEL_SOC_SSC"
introduces below build warnings:

drivers/misc/Kconfig:212:error: recursive dependency detected!

sound/soc/atmel/Kconfig:9:      symbol SND_ATMEL_SOC_SSC is selected by SND_AT91_SOC_SAM9G20_WM8731
sound/soc/atmel/Kconfig:18:     symbol SND_AT91_SOC_SAM9G20_WM8731 depends on ATMEL_SSC

SND_ATMEL_SOC_SSC needs ATMEL_SSC to pass compilation.
This patch remove the "select ATMEL_SSC" from SND_ATMEL_SOC_SSC to avoid above
warnings. And then ensures all the machine drivers that select SND_ATMEL_SOC_SSC
need to depend on ATMEL_SSC.

Lars-Peter Clausen 85e7652d89 ASoC: Constify snd_soc_dai_ops structs
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure")
introduced the possibility to have constant DAI ops structures, yet this is
barley used in both existing drivers and also new drivers being submitted,
although none of them modifies its DAI ops structure. The later is not
surprising since existing drivers are often used as templates for new drivers.
So this patch just constifies all existing snd_soc_dai_ops structs to eliminate
the issue altogether.

The patch was generated with the following coccinelle semantic patch:
// <smpl>

identifier ops;

-struct snd_soc_dai_ops ops =
