From 3cf2667b9f8b2c2fe298a427deb399e52321da6b Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Mon, 4 Feb 2013 13:37:21 +0000 Subject: fb: add support for drivers not needing VT switch at suspend/resume time Use the new PM routines to indicate whether we need to VT switch at suspend and resume time. When a new driver is bound, set its flag accordingly, and when unbound, remove it from the PM's console tracking list. Signed-off-by: Jesse Barnes Acked-by: Rafael J.
