[PATCH 5.10 117/135] interconnect: Zero initial BW after sync-state

From: Greg Kroah-Hartman
Date: Tue Aug 10 2021 - 13:50:26 EST


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.
