Subject: rtl8187: Remove deprecated 'qual' from returned RX status
X-Git-Tag: v2.6.33-rc1~388^2~449^2~16
X-Git-Url: https://bbs.cooldavid.org/git/?a=commitdiff_plain;h=70d9f405d09e334b609702d88ee03b6119c4b45e;p=net-next-2.6.git

rtl8187: Remove deprecated 'qual' from returned RX status

The qual member of ieee80211_rx_status is deprecated. As a result, this
driver no longer needs to calculate a quality value.
