# Handle camera service around suspend/resume.
#
# v4l2-relayd must be stopped before suspend to avoid GStreamer crashes,
# then restarted after resume once the camera hardware is ready.
#
# Avoid unloading/reloading IPU7 kernel modules from the sleep hook. Module
# reprobe during resume can hit fragile kernel PM paths and make wake less
# reliable than a recoverable camera failure.
