Subject: mac80211: remove ieee80211_tx_info from rate_control_apply_mask signature
X-Git-Tag: firefly_0821_release~176^2~1159^2~155^2~7
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=35225eb7a5589407299033bfa7e1ac723b17e2b5;p=firefly-linux-kernel-4.4.55.git

mac80211: remove ieee80211_tx_info from rate_control_apply_mask signature

Remove unnecessary ieee80211_tx_info pointer from rate_control_apply_mask
signature. rate_control_apply_mask() will be used to define a ratemask in
rate_control_set_rates() for station rate table
