X-Git-Tag: v3.5~24^2~24^2~6
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=472dd35ccbd999a6cb2994c318ca16edf65c4359;p=karo-tx-linux.git

mac80211: correct size the argument to kzalloc in minstrel_ht

msp has type struct minstrel_ht_sta_priv not struct minstrel_ht_sta.

(This incorporates the fixup originally posted as "mac80211: fix kzalloc
memory corruption introduced in minstrel_ht". -- JWL)
