Yes, other cameras may be affected, but they still can work well, so the patch still makes sense. > > Have you tried to investigate why suspend/resume fails for the above-mentioned > camera, instead of working around the problem ? 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.
