From a2e1d52a32eab53f8ab03c4023310f65aaa054a7 Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Mon, 31 Mar 2008 15:53:44 +0200 Subject: rt2x00: Remove MAC80211_LEDS dependency Implement triggers inside rt2x00 itself based on input from mac80211. This replaces the method of using the mac80211 trigger events which do not work for USB drivers due to the scheduling requirement. After this patch RT2500USB_LEDS and RT73USB_LEDS no longer need to be tagged as broken since they now support LED handling again without having to check for in_atomic().
