From f7018c21350204c4cf628462f229d44d03545254 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Thu, 13 Feb 2014 15:31:38 +0200 Subject: video: move fbdev to drivers/video/fbdev The drivers/video directory is a mess. It contains generic video related files, directories for backlight, console, linux logo, lots of fbdev device drivers, fbdev framework files. Make some order into the chaos by creating drivers/video/fbdev directory, and move all fbdev related files there. No functionality is changed, although I guess it is possible that some subtle Makefile build order related issue could be created by this patch.
