Subject: [PATCH] keucr: removed unnecessary variables and comments

From: Laura Lawniczak <laura.lawniczak@...glemail.com>

blen and bn were only used in commented code fragments.
since comments should be informative and not for storing old
code, both, commented code and variables, were removed.

  this one is against latest gregkh/staging-next, and at least for me applies
  cleanly.
