I will take this.
I do see two warnings, but they both seem to be valid and recent,
though, so I have no issues with the spurious cases.
Warning #1:
sound/soc/qcom/lpass-platform.c: In function ‘lpass_platform_pcmops_open’:
sound/soc/qcom/lpass-platform.c:83:29: warning: ‘dma_ch’ may be used
uninitialized in this function [-Wmaybe-uninitialized]
drvdata->substream[dma_ch] = substream;
~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~
and 'dma_ch' usage there really is crazy and wrong. Broken by
022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data usage")
Warning #2 is not a real bug, but it's reasonable that gcc doesn't
know that storage_bytes (chip->read_size) has to be 2/4. Again,
introduced recently by commit 231147ee77f3 ("iio: maxim_thermocouple:
Align 16 bit big endian value of raw reads"), so you didn't see it.
drivers/iio/temperature/maxim_thermocouple.c: In function
‘maxim_thermocouple_read_raw’:
drivers/iio/temperature/maxim_thermocouple.c:141:5: warning: ‘ret’
may be used uninitialized in this function [-Wmaybe-uninitialized]
if (ret)
^
drivers/iio/temperature/maxim_thermocouple.c:128:6: note: ‘ret’ was
declared here
int ret;
^~~
and I guess that code can just initialize 'ret' to '-EINVAL' or
something to just make the theoretical "somehow we had a wrong
chip->read_size" case error out cleanly.
