Subject: cfg80211: fix refcount leak
X-Git-Tag: v2.6.31-rc3~40^2~5^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=2dce4c2b5f0b43bd25bf9ea6ded06b7f8a54c91f;p=platform%2Fupstream%2Fkernel-adaptation-pc.git

cfg80211: fix refcount leak

The code in cfg80211's cfg80211_bss_update erroneously
grabs a reference to the BSS, which means that it will
never be freed.
