X-Git-Tag: v4.7-rc1~154^2~146^2~8^2~19 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cd84042ce9040ad038e958bc67a46fcfc015c736;p=karo-tx-linux.git ath9k: Add a module parameter to invert LED polarity. The LED can be active high instead of active low on some hardware. Add the led_active_high module parameter. It defaults to -1 to obey platform data as before. Setting the parameter to 1 or 0 will force the LED respectively active high or active low.
