Currently video driver is voting for venus0-ebi path during buffer processing with an average bandwidth of all the instances and unvoting during session release. While video streaming when we try to do XO-SD using the command "echo mem > /sys/power/state command" , device is not entering to suspend state and from interconnect summary seeing votes for venus0-ebi Corrected this by voting for venus0-ebi path in venus_runtime_resume() and unvote during venus_runtime_suspend().
