From 0bae35e14b68f5e7075bc96e5ea608b42bdf8f59 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 2 Dec 2010 14:31:14 -0800 Subject: [PATCH] leds: fix up dependencies It's not useful to build LED triggers when there's no LEDs that can be triggered by them. Therefore, fix up the dependencies so that this cannot happen, and fix a few users that select triggers to depend on LEDS_CLASS as well (there is also one user that also selects LEDS_CLASS, which is OK).
