Subject[PATCH 3/4] interconnect: qcom: smd845: Use icc_sync_state
Date
Lowering the bandwidth on the bus might have negative consequences if
it's done before all consumers had a chance to cast their vote. Let's
return the maximum amount of bandwidth as initial value. This bandwidth
level would be maintained until all consumers have probed.
