The DAI counting code doesn't propagate errors when the number of
maximum links is exceeded, which causes subsequent initialization code
to continue to run and that eventually leads to memory corruption with
the code trying to access memory that is out of bounds.
Fix this by propagating errors when the maximum number of links is
reached, which ensures that the driver fails to load and prevents the
memory corruption.

soc_pcm_params_symmetry() checks CPU / Codec symmetry.
Unfortunately there was bug on it (= A) which didn't check Codec.
But is back by (B).
A: v5.7: commit c840f7698d ("ASoC: soc-pcm: Merge for_each_rtd_cpu/codec_dais()")
B: v5.12: commit 3a90672111 ("ASoC: soc-pcm: cleanup soc_pcm_params_symmetry()")
In total,
old - v5.6 (= Generation-1):
symmetric_rate : DAI_Link / CPU / Codec
symmetric_channels : DAI_Link / CPU / Codec
symmetric_sample_bits : DAI_Link / CPU / Codec
v5.7 - v5.11 (= Generation-2): (= because of bug by (A))
symmetric_rate : DAI_Link / CPU
symmetric_channels : DAI_Link / CPU / Codec
symmetric_sample_bits : DAI_Link / CPU / Codec
v5.12 - (= Generation-3): (= back by (B))
symmetric_rate : DAI_Link / CPU / Codec
symmetric_channels : DAI_Link / CPU / Codec
symmetric_sample_bits : DAI_Link / CPU / Codec
OTOH, we can use DPCM which is configured by FE / BE.
Both FE / BE uses dummy-DAI.
FE: CPU <-> dummy-DAI
BE: dummy-DAI <-> Codec
One note is that we can use .be_hw_params_fixup in DPCM case.
This means BE settings might be fixuped/updated by FE.
This feature is used for example on MIXer case.
It can be happen not only for rate, but for channels/sample_bits too.
Because of these reasons, below issue happen on
Generation-1 / Generation-3, if...
1) Sound Card used DPCM
2) It exchanges rate to 48kHz by using .be_hw_params_fixup()
3) Codec had symmetric_rate = 1
I didn't confirm, but maybe same things happen
if it exchanged channels/sample_bits at Generation-1/2/3 too.

soc_pcm_params_symmetry() checks by below

for_each_rtd_cpu_dais(rtd, i, cpu_dai)
if (cpu_dai->xxx && cpu_dai->xxx != d.xxx) {
dev_err(rtd->dev, "...");
return -EINVAL;
}
Because of above reason 3) (= Codec had symmetric_rate = 1)
BE can't ignore "if (symmetric)".
At 1st aplay, soc_pcm_params_symmetry() ignores it,
because dummy-DAI->rate is 0.
After this check, each DAI sets/keep settings.
In above sample case, BE gets 48000 and FE gets 44100,
and it happen BE -> FE order.
Because DPCM is sharing *same* dummy-DAI,
dummy-DAI sets as 48000 by BE, and is overwrote by 44100 by FE.
This settings never be cleaned (= a) after 1st aplay,
because dummy-DAI is used from FE/BE, never be last user (b).
static int soc_pcm_hw_clean(...)
{
...
for_each_rtd_dais(rtd, i, dai) {
...
(b) if (snd_soc_dai_active(dai) == 1)
(a) soc_pcm_set_dai_params(dai, NULL);
...
}
...
}
At 2nd aplay, BE gets 48000 but dummy-DAI is keeping 44100,
soc_pcm_params_symmetry() checks will fail.
To solve this issue, this patch ignores dummy-DAI
at soc_pcm_params_symmetry()

__soc_pcm_params_symmetry() macro is using "name" as parameter
which will be exchanged to rate/channles/sample_bit, like below
dai->name => dai->rate
dai->name => dai->channels
dai->name => dai->sample_bit
But, dai itself has "name". This means
1) It is very confusable naming
2) It can't use dai->name
This patch use "xxx" instead of "name"

A DAI link has 3 components:
* CPU
* platform
* codec(s)
A component is specified via:
* name
* of_node
* dai_name
In order to avoid confusion when building a sound card we disallow
matching by both name and of_node (1).
soc_check_tplg_fes allows overriding certain BE links by overriding
BE link name. This doesn't work well if BE link was specified via DT,
because we end up with a link with both name and of_node specified
which is conflicting with (1).
In order to fix this we need to:
* override of_node if component was specified via DT
* override name, otherwise.

There are few instances of KUNIT tests that are not properly defined.
This commit focuses on correcting these issues to match the standard
defined in the Documentation.
Issues Fixed:
- tests should end in KUNIT_TEST, some fixes have been applied to
correct issues were KUNIT_TESTS is used or KUNIT is not mentioned.
- Tests should default to KUNIT_ALL_TESTS
- Tests configs tristate should have if !KUNIT_ALL_TESTS
No functional changes other than CONFIG name changes
Changes since v2:
- Split patch 1 by subcomponents
- fix issues where config was *KUNIT_TEST_TEST
- properly threaded/chained messages

2.30.2
Current rsnd needs to call .prepare (P) for clock settings,
.trigger for playback start (S) and stop (E).
It should be called as below from SSI point of view.
P -> S -> E -> P -> S -> E -> ...
But, if you used MIXer, below case might happen
(2)
1: P -> S ---> E -> ...
2: P ----> S -> ...
(1) (3)
P(1) setups clock, but E(2) resets it. and starts playback (3).
In such case, it will reports "SSI parent/child should use same rate".
rsnd_ssi_master_clk_start() which is the main function at (P)
was called from rsnd_ssi_init() (= S) before,
but was moved by below patch to rsnd_soc_dai_prepare() (= P) to avoid
using clk_get_rate() which shouldn't be used under atomic context.
commit 4d230d1271 ("ASoC: rsnd: fixup not to call clk_get/set
under non-atomic")
Because of above patch, rsnd_ssi_master_clk_start() is now called at (P)
which is for non atomic context. But (P) is assuming that spin lock is
*not* used.
One issue now is rsnd_ssi_master_clk_start() is checking ssi->xxx
which should be protected by spin lock.
After above patch, adg.c had below patch for other reasons.
commit 06e8f5c842 ("ASoC: rsnd: don't call clk_get_rate()
under atomic context")
clk_get_rate() is used at probe() timing by this patch.
In other words, rsnd_ssi_master_clk_start() is no longer using
clk_get_rate() any more.
This means we can call it from rsnd_ssi_init() (= S) again which is
protected by spin lock.
This patch re-move it to under spin lock, and solves
1. checking ssi->xxx without spin lock issue.
2. clk setting / device start / device stop race condition.

Hi Mark
This patch-set is for v2 of Multi-CPU/Codec support,
and some cleanups.
v1 had patch-conflict on simple-card / audio-graph with below.
v2 was solved it.
fa74c223b6
("ASoC: simple-card: fix possible uninitialized single_cpu local variable")
I want to add new audio-graph-card2 driver which can support
not only DPCM, but also Multi-CPU/Codec, and Codec2Codec.
And it is also supporting audio-graph-card2 base custom driver.
But before supporting such driver, we need to cleanup existing
simple-card / audio-graph, because these and new driver are
sharing code.
