New Revision: 240655
URL: http://svn.freebsd.org/changeset/base/240655

Log:
  Fix panics on attempt to dereference uninitizlized pointer, returned via
  'path' argument of ofw_parsedev() if devspec refers raw device with no path.
  
  For example, `ls /pci@1f,0/ide@d/disk@0,0:a/` works fine, while
  `ls /pci@1f,0/ide@d/disk@0,0:a` panicked before this change.
