    Subject[PATCH 3.16 271/346] nl80211: validate number of probe response CSA counters
    3.16.39-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Johannes Berg <johannes.berg@intel.com>

    commit ad5987b47e96a0fb6d13fea250e936aed000093c upstream.

    Due to an apparent copy/paste bug, the number of counters for the
    beacon configuration were checked twice, instead of checking the
    number of probe response counters. Fix this to check the number of
    probe response counters before parsing those.

    Fixes: 9a774c78e211 ("cfg80211: Support multiple CSA counters")
