commit 1c49f35e9e9156273124a0cfd38b57f7a7d4828f upstream.
Fix following warning: vt8500lcdfb.c: In function 'vt8500lcd_blank': vt8500lcdfb.c:229:6: warning: this statement may fall through [-Wimplicit-fallthrough=] if (info->fix.visual == FB_VISUAL_PSEUDOCOLOR || ^ vt8500lcdfb.c:233:2: note: here case FB_BLANK_UNBLANK: ^~~~
Adding a simple "fallthrough;" fixed the warning. The fix was build tested.
