Subject: mac80211: return the RSSI in dBm
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3a7bba649eaaa2068aa6e86ed8bcd10245d1f817;p=linux-beck.git

mac80211: return the RSSI in dBm

For the sake of speed of calculation and number accuracy,
mac80211 tracks the RSSI in dBm * 16. But it forgot to
divide back by 16 when the RSSI is asked by the driver.
