svn commit: r259886 - head/sys/dev/ie

[Bjoern A. Zeeb]

Author: bz
Date: Wed Dec 25 20:15:48 2013
New Revision: 259886
URL: http://svnweb.freebsd.org/changeset/base/259886

Log:
  Bite the bullet and start removing the first compile time warnings
  by removing unsued file local functions and then unused callees.
  A lot more warnings to resolve but someone had to break the ice.
  
  MFC after:	10 days
  X-Comment:	I am not the new maintainer; chime in, it's ours.
