video: move fbdev to drivers/video/fbdev 2014-04-17T05:10:19+00:00 Tomi Valkeinen tomi.valkeinen@ti.com 2014-02-13T13:31:38+00:00 f7018c21350204c4cf628462f229d44d03545254 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.
