The pin pointed above is default LED GPIO (8) for AR9287. For WNR2200 it is not connected anywhere - pin 0 drives blue WLAN LED instead - but initialization code is missing that information. This fix calls ap9x_pci_setup_wmac_led_pin() function at device setup, forcing WLAN LED pin to be 0 and removing redundant entry.
