svn commit: r212571 - user/weongyo/usb/sys/dev/usb/controller

[Weongyo Jeong]

Author: weongyo

New Revision: 212571
URL: http://svn.freebsd.org/changeset/base/212571

Log:
  Adds a XXX comment not sure that devclass_find(9) requires Giant
  holding.  Just looking the source code it looks it doesn't require it
  though it has a `devclasses' traversal loop.
