svn commit: r254593 - head/sys/arm/ti/am335x

[Ian Lepore]

Author: ian
Date: Wed Aug 21 04:49:58 2013
New Revision: 254593
URL: http://svnweb.freebsd.org/changeset/base/254593

Log:
  Make the noop clock successfully do nothing, because doing nothing and
  returning an error status (which the NULL method pointers caused) isn't
  nearly as useful.
