From 994efacdf9a087b52f71e620b58dfa526b0cf928 Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Fri, 9 Feb 2007 09:46:45 +0000 Subject: backlight/fbcon: Add FB_EVENT_CONBLANK The backlight class wants notification whenever the console is blanked but doesn't get this when hardware blanking fails and software blanking is used. Changing FB_EVENT_BLANK to report both would be a behaviour change which could confuse the console layer so add a new event for software blanking and have the backlight class listen for both.
