dpcm_fe_dai_startup() (= A) calls dpcm_set_fe_runtime() (= B) to setup
DPCM runtime. From *naming point of view*, it sounds like setup function
for FE.
(A) static int dpcm_fe_dai_startup(...)
{
...
(B) dpcm_set_fe_runtime(...);
...
}
But in dpcm_set_fe_runtime() (= B),
It setups FE by dpcm_runtime_setup_fe() (= X),
and setups BE by dpcm_runtime_merge_xxx() (= Y).
(B) static void dpcm_set_fe_runtime(...)

(X) dpcm_runtime_setup_fe(...);
^ dpcm_runtime_setup_be_format(...);
(Y) dpcm_runtime_setup_be_chan(...);
v dpcm_runtime_setup_be_rate(...);
}
These means that the function which is called as xxx_fe_xxx()
is setups both FE and BE. This is confusable and can be hot bed for bug.
Now dpcm_set_fe_runtime() (= B) is simple enough and confusable naming,
let's unpack it at dpcm_fe_dai_startup().

dpcm_init_runtime_hw() (= A) is used from dpcm_set_fe_runtime() (= B)
with for_each_rtd_cpu_dais() loop (= C), and it checks formats (= D).
(A) static void dpcm_init_runtime_hw(...)
{
...
^ if (runtime->hw.formats)
| (D1) runtime->hw.formats &= stream->formats;
(D) else
| (D2) runtime->hw.formats = stream->formats;

{
...
(C) for_each_rtd_cpu_dais(rtd, i, cpu_dai) {
...
(A) dpcm_init_runtime_hw(...);
}
}
If this for_each_rtd_cpu_dais() loop (= C) calls
dpcm_init_runtime_hw() (= A) multiple times, this means it is Multi-CPU.
If we focus to format operation at (D), using mask (= D1) is understandable
because it restricts unsupported format.
But, enabling format when zero format case (= D2) is very strange,
because it might enables unsupported format.
This runtime->hw.formats is initialized by ULLONG_MAX at soc_pcm_hw_init(),
thus becoming zero format means it can't use such format.
And doing this strange format operation is only here.
This patch removes strange format operation (= D2), and use standard
soc_pcm_hw_update_format() for it.

During testing John Stultz and Amit reported few array our bound issues
after enabling bound sanitizer
This patch series attempts to fix those!
changes since v1:
- make sure the wcd is not de-referenced without intialization
Srinivas Kandagatla (3):
ASoC: qcom: sdm845: Fix array out of bounds access
ASoC: qcom: sdm845: Fix array out of range on rx slim channels
ASoC: codecs: wcd934x: add a sanity check in set channel map

The ADSPCS_SPA is Set Power Active bit. To check if DSP is powered
down, we need to check ADSPCS_CPA, the Current Power Active bit.

set channel map can be passed with a channel maps, however if
the number of channels that are passed are more than the actual
supported channels then we would be accessing array out of bounds.
So add a sanity check to validate these numbers!

WCD934x has only 13 RX SLIM ports however we are setting it as 16
in set_channel_map, this will lead to array out of bounds error!
