[Patch v2][ 05/37] fbdev: Add the lacking FB_SYNC_* for matching the DISPLAY_FLAGS_*
From: Denis Carikli <hidden>

Subsystem:
framebuffer layer, the rest · Maintainers:
Helge Deller, Linus Torvalds
Without that fix, drivers using the fb_videomode_from_videomode function will not be able to get certain information because some DISPLAY_FLAGS_* have no corresponding FB_SYNC_*.
