Yes, other cameras may be affected, but they still can work well, so
the patch still
makes sense.

I have investigated the problem, and not found failures in the
suspend/resume path,
either .suspend or .resume callback return successful, but no stream packets are
received from camera any longer after resume from sleep. Once doing a unbind&
bind will make the camera work again.

Could you give any suggestions to help to find the root cause of the problem?



thanks,
