Hi Rong
(snip)Hmm... I still can't reproduce this issue.
I don't have gcc-6, thus can't try it.
Is this the issue ??
We can reproduce the warning with gcc-6 (gcc version 6.5.0 20181026Thank you for your feedback.
(Debian 6.5.0-2)),
and the warning can be closed if changed to "struct snd_soc_component
*component = NULL, *save = NULL;"
It sounds reasonable for me.
Can you post it ? or do you want me to do it ?
