| Subject: ath9k: Add a module parameter to invert LED polarity. |
| |
| From: Vittorio Gambaletta (VittGam) <linux-wireless@vittgam.net> |
| |
| commit cd84042ce9040ad038e958bc67a46fcfc015c736 upstream. |
| |
| 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. |
