Title:
  Backports doesn't compile against 3.13.0-30

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I attempted to compile backports-20140616 from here: http://drvbp1
  .linux-foundation.org/~mcgrof/rel-html/backports/ I was attemting to
  propose a solution for a poster on ubuntuforums.org by installing a
  possibly updated rtl8192ce driver. My usual process is to compile the
  driver myself through the 'make' step so as to demonstrate that the
  method I propose works.

  For reference, here is the original thread:
  http://ubuntuforums.org/showthread.php?t=2226009

  In my Ubuntu 14.04 system using kernel version 3.13.0-30-generic, the
  compile ends in many errors; please see attachment.

  On a whim, I booted into kernel 3.13.0-24-generic and the package
  compiles with four warnings:

  /home/chili/Downloads/backports-20140616/net/mac80211/iface.c:1099:2: warning: initialization from incompatible pointer type [enabled by default]
    .ndo_select_queue = ieee80211_netdev_select_queue,
    ^
  /home/chili/Downloads/backports-20140616/net/mac80211/iface.c:1099:2: warning: (near initialization for ‘ieee80211_dataif_ops.ndo_select_queue’) [enabled by default]
  /home/chili/Downloads/backports-20140616/net/mac80211/iface.c:1141:2: warning: initialization from incompatible pointer type [enabled by default]
    .ndo_select_queue = ieee80211_monitor_select_queue,
    ^
  /home/chili/Downloads/backports-20140616/net/mac80211/iface.c:1141:2: warning: (near initialization for ‘ieee80211_monitorif_ops.ndo_select_queue’) [enabled by default]

  But then continues to the end without error. The expected driver is
  built.

  Something has evidently changed between kernel versions that makes
  compilation of these packages fail. As the backports suite is often
  helpful to solve networking driver problems, it is important the the
  package be able to be compiled correctly.

  If you require further information or this should be posted elsewhere,
  please feel free to advise me.
