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