The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

sizeof(flexible-array-member) triggers a warning because flexible array
members have incomplete type[1]. There are some instances of code in
which the sizeof operator is being incorrectly/erroneously applied to
zero-length arrays and the result is zero. Such instances may be hiding
some bugs. So, this work (flexible-array member conversions) will also
help to get completely rid of those sorts of issues.

This issue was found with the help of Coccinelle.

The LPASS hardware allows configuring the MI2S SD lines to use
when playing/recording audio. However, at the moment the lpass-cpu
driver has SD0 hard-coded for mono/stereo (or additional fixed
SD lines for more channels).

For weird reasons there seems to be hardware that uses one of the
other SD lines for mono/stereo. For example, some Samsung devices
use an external Speaker amplifier connected to Quaternary MI2S.
For some reason, the SD line for audio playback was connected to
SD1 rather than SD0. (I have no idea why...)
At the moment, the lpass-cpu driver cannot be configured to work
for the Speaker on these devices.

The q6afe driver already allows configuring the MI2S SD lines
through the "qcom,sd-lines" device tree property, but this works
only when routing audio through the ADSP.

This commit adds a very similar configuration for the lpass-cpu driver.
It is now possible to add additional subnodes to the lpass device in
the device tree, to configure the SD lines for playback and/or capture.
E.g. for the Samsung devices mentioned above:

&lpass {
	dai@3 {
		reg = <MI2S_QUATERNARY>;
		qcom,playback-sd-lines = <1>;
	};
};

qcom,playback/capture-sd-lines takes a list of SD lines (0-3)
in the same format as the q6afe driver. (The difference here is that
q6afe has separate DAIs for playback/capture, while lpass-cpu has one
for both...)

For backwards compatibility with older device trees, the lpass-cpu driver
defaults to LPAIF_I2SCTL_MODE_8CH if the subnode for a DAI is missing.
This is equivalent to the previous behavior: Up to 8 channels can be
configured, and SD0/QUAT01 will be chosen when setting up a stream
with fewer channels.

This allows the speaker to work on Samsung MSM8916 devices
that use an external speaker amplifier.

PI tree.

Tested on Up2 with Digi+ IO (capture+playback) and Digi+ PRO (playback
with two local oscillators supported). The codec is clock master in
both cases.

Capture support has known clocking restrictions: the transmitter needs
to be active for the clock recovery, the "Tx Source" mixer set to
"S/PDIF RX". Playback will only work while capture is active.

When Capture is not desired, or when there is no RX connector, the "Tx
Source" mixer should be set to "AIF"

Merge series "SOF topology parsing updates" from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:

This series includes updates in the topology parser for DAIs
and their config.

The first three patches address the problem of sending the DAI
config to the DSP when there are multiple DAIs associated with
a DAI link.

The last patch deals with setting the default trigger order
for all links. Exceptions needed for HDA links are moved to
the DAI link fixup() callback.

The imx8 config keeps causing issues:

WARNING: unmet direct dependencies detected for SND_SOC_SOF_IMX8M
  Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=m] && SND_SOC_SOF_TOPLEVEL [=y] && SND_SOC_SOF_IMX_TOPLEVEL [=y] && IMX_DSP [=n]

This is complicated by two drivers having dependencies on both
platform specific drivers and the SND_SOC_SOF_OF framework code,
and using an somewhat obscure method to build them the same way
as the SOC_SOF_OF symbol (built-in or modular).

My solution now ensures that the two drivers can only be enabled
when the dependencies are met:

- When the platform specific drivers are built-in, everything is
  fine, as SOC_SOF_OF is either =y or =m

- When both are loadable modules, it also works, both for Kconfig
  and at runtime

- When the hardware drivers are loadable modules or disabled, and
  SOC_SOF_OF=y, prevent the IMX_SOF_OF drivers from being turned on,
  as this would be broken.

It seems that this is just an elaborate way to describe two tristate
symbols that have straight dependencies, but maybe I'm missing some
subtle point. It seems to always build for me now.

Now the trigger sequence is set to SND_SOC_DPCM_TRIGGER_POST for
SOF. This means FE will be stopped before BE, so BE will consume
invalid data and this generates huge pop noise. This sequence is
introduced for HDA DAI which requires SND_SOC_DPCM_TRIGGER_POST for
some reasons. Now set default trigger sequence to SND_SOC_DPCM_TRIGGER_PRE
for playback with all DAI and fix sequence only for HDA DAI.

  - SND_PXA2XX_SOC_EM_X270 [=m] && SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] && SND_PXA2XX_SOC [=m] && (MACH_EM_X270 [=n] || MACH_EXEDA [=n] || MACH_CM_X300 [=y]) && AC97_BUS [=n]=n

Change the dependency to allow either version of the AC97 library
code.

Old versions of gcc (tested on gcc-4.8) produce a warning for
correct code:

sound/soc/soc-compress.c: In function 'soc_compr_open':
sound/soc/soc-compress.c:75:28: error: 'component' is used uninitialized in this function [-Werror=uninitialized]
  struct snd_soc_component *component, *save = NULL;

Change the for_each_rtd_components() macro to ensure 'component'
gets initialized to a value the compiler does not complain about.
