fbdev: controlfb: Add missing modes to fix out of bounds access Dan's static analysis says: drivers/video/fbdev/controlfb.c:560 control_setup() error: buffer overflow 'control_mac_modes' 20 <= 21 Indeed, control_mac_modes[] has only 20 elements, while VMODE_MAX is 22, which may lead to an out of bounds read when parsing vmode commandline options. The bug was introduced in v2.4.5.6, when 2 new modes were added to macmodes.h, but control_mac_modes[] wasn't updated: https://kernel.opensuse.org/cgit/kernel/diff/include/video/macmodes.h?h=v2.5.2&id=29f279c764808560eaceb88fef36cbc35c529aad Augment control_mac_modes[] with the two new video modes to fix this.

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.
