[PATCH] fbdev: fix possible NULL pointer derefernce

The spec->modedb can be NULL by fb_create_modedb(). And also smatch says: drivers/video/fbdev/core/fbmon.c:975 fb_edid_to_monspecs() error: potential null dereference 'specs->modedb'. (fb_create_modedb returns null) Signed-off-by: Daeseok Youn --- drivers/video/fbdev/core/fbmon.c |3 +++ 1
