code.

ASoC: sprd: Switch to use list_entry_is_head() helper
Since we got list_entry_is_head() helper in the generic header,
we may switch driver to use it. This eliminates the need
in additional variable.

ASoC: Remove dev_err() usage after platform_get_irq()
We don't need dev_err() messages when platform_get_irq() fails now that
platform_get_irq() prints an error message itself when something goes
wrong. Let's remove these prints with a simple semantic patch.

// <smpl>
@@
expression ret;
struct platform_device *E;
@@

ret =
(
platform_get_irq(E, ...)
|
platform_get_irq_byname(E, ...)
);

if ( \( ret < 0 \| ret <= 0 \) )
{
(
-if (ret != -EPROBE_DEFER)
-{ ...
-dev_err(...);
-... }
|
...
-dev_err(...);
)
...
}
// </smpl>

While we're here, remove braces on if statements that only have one
statement (manually).

ASoC: sprd: Fix to use list_for_each_entry_safe() when delete items
Since we will remove items off the list using list_del() we need
to use a safe version of the list_for_each_entry() macro aptly named
list_for_each_entry_safe().

ASoC: sprd: Fix return value check in sprd_mcdt_probe()
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().

ASoC: sprd: Add Spreadtrum multi-channel data transfer support
On Spreadtrum platform, the audio subsystem will use the multi-channel
data transfer controller to transfer sound stream between audio subsystem
and other AP/CP subsystem.

It can support 10 DAC channel and 10 ADC channel, and each channel has
512 bytes depth data fifo. Moreover each channel can be used DMA mode
or interrupt mode to transfer data.
