Hi ALSA team,
This is wrt soc_compr_open_fe() call result in warning in API triggered
from it snd_soc_runtime_activate(fe, stream)..
Due to lock taken is &fe->card->mutex, but expected to take
&fe->pcm_mutex.
Below line results in warning since pcm_mutex lock is not taken..
void snd_soc_runtime_activate(struct snd_soc_pcm_runtime *rtd, int
stream)
{
...
lockdep_assert_held(&rtd->pcm_mutex);
}
Warning seen as below ->

As this release it at the end of life with 3.18.92 being released just today
(and yours 3.18.71 comes from 13-Sep-2017) it is very unlikely anyone would
bother to look at this...

can you explain what are you trying, since I don't see this warning, do you
see this warning always or sometimes?
Btw this is common path for compress and pcm, so even a pcm should
potentially trigger this...
