Subject: interconnect: Zero initial BW after sync-state
From: Mike Tipton <mdtipton@xxxxxxxxxxxxxx>
commit 456a9dace42ecfcec7ce6e17c18d1985d628dcd0 upstream.
The initial BW values may be used by providers to enforce floors. Zero
these values after sync-state so that providers know when to stop
enforcing them.
Fixes: b1d681d8d324 ("interconnect: Add sync state support")
