Kees Cook a86854d0c5 treewide: devm_kzalloc() -> devm_kcalloc() 
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:

        devm_kzalloc(handle, a * b, gfp)

with:
        devm_kcalloc(handle, a * b, gfp)

as well as handling cases of:

        devm_kzalloc(handle, a * b * c, gfp)

with:

        devm_kzalloc(handle, array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        devm_kcalloc(handle, array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        devm_kzalloc(handle, 4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

The Coccinelle script used for this was:

Revert that commit for now, along with f11a5c27f9 (ASoC: core: Add

ASoC: core: Allow topology to override machine driver FE DAI link config. 
Machine drivers statically define a number of DAI links that currently
cannot be changed or removed by topology. This means PCMs and platform
components cannot be changed by topology at runtime AND machine drivers
are tightly coupled to topology.

This patch allows topology to override the machine driver DAI link config
in order to reuse machine drivers with different topologies and platform
components. The patch supports :-

1) create new FE PCMs with a topology defined PCM ID.
2) destroy existing static FE PCMs
3) change the platform component driver.
4) assign any new HW params fixups.

The patch requires no changes to the machine drivers, but does add some
platform component flags that the platform component driver can assign
before loading topologies.

soc-core: don't call kfree() for component 
When driver register its component to ALSA SoC, almost all drivers are
using snd_soc_register_component(), but soc-generic-dmaengine-pcm is
using snd_soc_add_component().

Existing component function had been assumed that registered component
was allocated, and it calling kfree() for it.
But, the user who used snd_soc_add_component() doesn't.

This patch uses devm_kzalloc() instead of kzalloc() for component,
and doesn't call kree() anymore.
This patch fixes commit be7ee5f32a ("ASoC: soc-generic-dmaengine-pcm:
replace platform to component").
Allwinner H3 SoC will crash without this patch.

 important fixes in here, mainly a fix for I/O on a number of devices
 caused by some of the component rework and a fix for a potential issue
 if more than one component in a link provides compressed operations.
 The I/O fixes are particularly important as the problem causes a power
 regression on a number of OMAP platforms.

Kuninori Morimoto 7dd5d0d954 ASoC: soc-core: add component lookup functions 
ALSA SoC platform/codec will be replaced to component soon.
This means 1 device might have multiple components. But current
unregister component function only checks "dev" to find it.
This means, unexpected component might be unregistered by current
function.
But, it is no problem if driver registered only 1 component.

To prepare avoid this issue, this patch adds new component
lookup function. it finds component by "dev" and "driver name".

Here, the reason why it uses "driver name" is that "component name"
was created by fmt_single_name() and difficult to use it from driver.
Driver of course knows its "driver name", thus, using it is more easy.

Kuninori Morimoto 7ba236ce58 ASoC: add Component level set_bias_level 
In current ALSA SoC, Codec only has set_bias_level feature.
Codec will be merged into Component in next generation ALSA SoC,
thus current Codec specific feature need to be merged into it.
This is glue patch for it.

Codec driver has .idle_bias_off for dapm bias. But Component
driver doesn't have it, and dapm->idle_bias_off is set as "true".
To keep compatibility, this patch adds "idle_bias_on" instead of
".idle_bias_off" on Component driver.
dapm->idle_bias_off will be set by inverted idle_bias_on.

When we replace Codec to Component, the driver which has
".idle_bias_off = true" is just remove it,
and the driver which doesn't have it will have new
".idle_bias_on = true".
