svn commit: r266666 - stable/9/sys/dev/usb/controller

[Hans Petter Selasky]

Author: hselasky
Date: Sun May 25 18:15:37 2014
New Revision: 266666
URL: http://svnweb.freebsd.org/changeset/base/266666

Log:
  MFC r266541:
  
  - Fix a bug where the TLBPC value was forced to being odd for IN
  direction isochronous transfers.
  - Remove setting of fields which does not belong to the respective
  TRBs. These fields are currently set as zero and this is more a
  cosmetic change.
