Subject: mac80211: fix the for_each_sta_info macro
X-Git-Tag: v2.6.36-rc1~571^2~107^2~135
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=38bdb650f902d275d6b2f9c2d8247fd960525583;p=profile%2Fcommon%2Fkernel-common.git

mac80211: fix the for_each_sta_info macro

Because of an ambiguity in the for_each_sta_info macro, it can
currently only be used if the third parameter is set to 'sta'.
Fix this by renaming the parameter to '_sta'.
