Indeed, sorry for the confusion.
The original mail only went to linux-media, not lkml, which is why I
picked the wrong one from the archive. Here's the patch:
https://lore.kernel.org/linux-media/20200909112921.5116-1-weiyongjun1@huawei.com/
Take care

mmpcam_runtime_suspend/mmpcam_runtime_resume also should be cared, I'll adjust my patch based on it.
