New Revision: 235603
URL: http://svn.freebsd.org/changeset/base/235603

Log:
  Do not double-reference the found vm object in cdev_pager_lookup().
  vm_pager_object_lookup() already referenced the object.
  
  Note that there is no in-tree consumers of cdev_pager_lookup(). The
  only known user of the function is i915 gem driver, which is not yet
  imported. This should make the KPI change minor.
