svn commit: r355022 - head/sys/dev/random

[Conrad Meyer]

Author: cem
Date: Fri Nov 22 20:24:15 2019
New Revision: 355022
URL: https://svnweb.freebsd.org/changeset/base/355022

Log:
  random(4): De-export random_sources list
  
  The internal datastructures do not need to be visible outside of
  random_harvestq, and this helps ensure they are not misused.
  
  No functional change.
