New Revision: 228971
URL: http://svn.freebsd.org/changeset/base/228971

Log:
  For sys/dev/ce/tau32-ddk.c, disable the following warning when building
  with clang:
  
  sys/dev/ce/tau32-ddk.c:1228:37: warning: implicit truncation from 'int' to bitfield changes value from 65532 to 8188 [-Wconstant-conversion]
  
  Since this file is obfuscated C, we can never determine (in a sane way,
  at least :) if this points to a real problem or not.  The driver has
  been in the tree for more than five years, so it most likely isn't.
  
  MFC after:	1 week
