Break this line up at the 70 character mark.

Use your full legal name as if you were signing a legal document to
certify that you haven't stolen this code from Darl McBride.

Move this to the previous line:

		result = hfa384x_usbctlx_complete_sync(hw, ctlx, cmplt);

But generally this is a nice little cleanup.  Please resend a v2
version.
