Subject: [PATCH] video: vt8500lcdfb: fix fallthrough warning
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.
