From 4e7ca40dbff522691b13dd9b5ed41891e6c68e1a Mon Sep 17 00:00:00 2001 From: Ian Armstrong Date: Sun, 19 Oct 2008 18:58:26 -0300 Subject: V4L/DVB (9328): ivtvfb: FB_BLANK_POWERDOWN turns off video output When using FBIOBLANK, FB_BLANK_POWERDOWN will now switch off the video output. Since some televisions turn themselves off after a while with no signal, this is the closest we can get to power-saving.
