From: Arjan van de Ven <arjan@linux.intel.com> Subject: [PATCH] fastboot: turn the USB hostcontroller initcalls into async initcalls
the USB host controller init calls take a long time, mostly due to a "minimally 100 msec" delay *per port* during initialization. These are prime candidates for going in parallel to everything else.
The USB device ordering is not affected by this due to the serialized-within-eachother property of async initcalls.
