Subject: [PATCH] [ath5k][leds] Ability to disable leds support. If leds support enabled do not force mac802.11 leds layer selection.
Hi!
Here is the patch to disable ath5k leds support on build stage.
However if the leds support was enabled do not force selection of 802.11 leds layer.
Depency on LEDS_CLASS is kept.
Suggestion given by Pavel Roskin and Bob Copeland applied.
Regards,
--Dima
