+Subject: [PATCH] fastboot: hold the BKL over the async init call sequence
+
+Regular init calls are called with the BKL held; make sure
+the async init calls are also called with the BKL held.
+While this reduces parallelism a little, it does provide
+lock-for-lock compatibility. The hit to prallelism isn't too
+bad, most of the init calls are done immediately or actually
+block for their delays.
