      ASoC: pxa: rename to snd_soc_component_read() · 2f86f20b
      Kuninori Morimoto authored 
      We need to use snd_soc_component_read()
instead of     snd_soc_component_read32()

This patch renames _read32() to _read()

      ASoC: soc-component: use io_mutex correctly · e8712315
      Kuninori Morimoto authored 
      component has io_mutex, but it had been used at
snd_soc_component_update_bits_legacy() only which does read and write.

	static int snd_soc_component_update_bits_legacy(...)
	{
		...
=>		mutex_lock(&component->io_mutex);
		...
		old = snd_soc_component_read(...);
		...
		ret = snd_soc_component_write(...);
		...
=>		mutex_unlock(&component->io_mutex);
		...
	}

It is pointless if it is not used with both read and write functions.
This patch uses io_mutex correctly with read/write.
Here, xxx_no_lock() is local functions.

	static int snd_soc_component_read(...)
	{
		...
=>		mutex_lock(&component->io_mutex);
		val = soc_component_read_no_lock(...);
=>		mutex_unlock(&component->io_mutex);
		...
	}

	static int snd_soc_component_write(...)
	{
		...
=>		mutex_lock(&component->io_mutex);
		ret = soc_component_write_no_lock(...);
=>		mutex_unlock(&component->io_mutex);
		...
	}

	static int snd_soc_component_update_bits_legacy(...)
	{
		...
=>		mutex_lock(&component->io_mutex);
		...
		old = soc_component_read_no_lock(...);
		...
		ret = soc_component_write_no_lock(...);
		...
=>		mutex_unlock(&component->io_mutex);
		...
	}

      ASoC: soc-component: merge snd_soc_component_read() and snd_soc_component_read32() · cf6e26c7
      Kuninori Morimoto authored 
      We had read/write function for Codec, Platform, etc,
but these has been merged into snd_soc_component_read/write().

Internally, it is using regmap or driver function.
In read case, each styles are like below

regmap
	ret = regmap_read(..., reg, &val);

driver function
	val = xxx->read(..., reg);

Because of this kind of different style, to keep same read style,
when we merged each read function into snd_soc_component_read(),
we created snd_soc_component_read32(), like below.
commit 738b49ef ("ASoC: add snd_soc_component_read32")

(1)	val = snd_soc_component_read32(component, reg);

(2)	ret = snd_soc_component_read(component, reg, &val);

Many drivers are using snd_soc_component_read32(), and
some drivers are using snd_soc_component_read() today.

In generally, we don't check read function successes,
because, we will have many other issues at initial timing
if read function didn't work.

Now we can use soc_component_err() when error case.
This means, it is easy to notice if error occurred.

This patch aggressively merge snd_soc_component_read() and _read32(),
and makes snd_soc_component_read/write() as generally style.

This patch do
	1) merge snd_soc_component_read() and snd_soc_component_read32()
	2) it uses soc_component_err() when error case (easy to notice)
	3) keeps read32 for now by #define
	4) update snd_soc_component_read() for all drivers

Because _read() user drivers are not too many, this patch changes
all user drivers.
