Wolfram Sang 0d0a995aa8 ASoC: spear: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Lars-Peter Clausen bde24030b5 ASoC: spear: spdif_out: Fix mute control
For controls registers with snd_soc_add_dai_controls snd_kcontrol_chip() returns
a pointer to the DAI, not to the CODEC.

Stephen Warren e1771bcf99 ASoC: SPEAr: remove custom DMA alloc compat function
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().

Stephen Warren ede38884ac ASoC: SPEAr: get rid of spear-pcm-audio struct device
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().

Tushar Behera fc09cfbe3e ASoC: spear: Convert to use devm_ioremap_resource
Commit 75096579c3 ("lib: devres: Introduce devm_ioremap_resource()")
introduced devm_ioremap_resource() and deprecated the use of
devm_request_and_ioremap().

devm_request_mem_region is called in devm_ioremap_resource(). Hence that
part can also be removed.

Since devm_ioremap_resource prints error message on failure, there is
no need to print an explicit warning message.

Uwe Kleine-König d8f4e17fdd ASoC: SPEAr spdif_{in,out}: fix fallout of previous cleanup
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.
