svn commit: r239822 - stable/8/sys/boot/common

[John Baldwin]

Author: jhb
Date: Wed Aug 29 12:35:50 2012
New Revision: 239822
URL: http://svn.freebsd.org/changeset/base/239822

Log:
  MFC 237338:
  Don't return an error if a kld does not contain any modules (e.g. a
  kld that only contained a sysctl).  The kernel linker allows such
  modules, so the boot loader should not reject them.
