Subject: [PATCH] framework/flow: Fix circular import
Date: Mon, 31 Jan 2022 17:09:37 -0500
Message-ID: <20220131220937.38772-1-ohilyard@iol.unh.edu> (raw)

From: Owen Hilyard <ohilyard@iol.unh.edu>

Some of the re-organization to DTS caused a previously ok circular
import to make the flow generator crash. Moving to local imports has
fixed this.
