media: venus: core: vote for video-mem path
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(). suspend") Fixes: 07f8f22a33a9e ("media: venus: core: remove CNOC voting while device Signed-off-by: Mansur Alisha Shaik <mansur@codeaurora.org> Reviewed-by: Stephen Boyd <swboyd@chromium.org> Signed-off-by: Stanimir Varbanov <stanimir.varbanov@linaro.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
