From 1bd465e6b0e2b559db47420fea686507a01cfab0 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Sat, 10 Jan 2009 18:54:39 +0000 Subject: leds: allow led-drivers to use a variable range of brightness values This patch allows drivers to override the default maximum brightness value of 255. We take care to preserve backwards-compatibility as much as possible, so that user-space ABI doesn't change for existing drivers. LED trigger code has also been updated to use the per-LED maximum.
