These snd_soc_dai_ops structures are only stored in the ops field of
a snd_soc_dai_driver structure, which is const. Thus, the
snd_soc_dai_ops structures can be const too.
Done with the help of Coccinelle.

functions
Omit an extra message for a memory allocation failure in these functions.
This issue was detected by using the Coccinelle software.

platform_get_irq() returns an error code, but the spdif_in driver
ignores it and always returns -EINVAL. This is not correct, and
prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error:

Print error message and propagate the return value of platform_get_irq
on failure.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

spear_pcm_request_chan() is almost identical to
dmaengine_pcm_compat_request_channel(), with the exception that the
latter:
a) Assumes that the DAI DMA data is a struct snd_dmaengine_dai_dma_data
pointer rather than some custom type.
b) dma_data->filter_data rather than dma_data should be passed to
snd_dmaengine_pcm_request_channel() as the filter data.
Make minor changes to the SPEAr DAI drivers so that those two conditions
are met. This allows removal of the custom .compat_request_channel().

Modify the SPEAr PCM driver so that it's a utility library that can be
registered on each DAI, rather than a separate struct device. This is
more in line with how many recent DT-converted platforms operate, and
avoids the need for yet another struct device.
This is also required as a pre-cursor to removing
spear_pcm_request_chan().

The patch that resulted in
bfcc74e (ASoC: SPEAr spdif_{in,out}: use devm for clk and a few
more cleanups)
was broken and applied on a newer tree than it was created for. So
bfcc74e introduced unbalanced clk handling, two warnings about unused
variables and passed 3 arguments to a function only taking 2. This
commit fixes that.

devm_request_and_ioremap instead of devm_ioremap to properly register the

This allows us to access the DAI DMA data when we create the PCM. We'll use
this when converting spear to generic DMA engine PCM driver.
