Subject[PATCH] fbdev: replace snprintf in show functions with sysfs_emit
Date
From: Yang Guang <yang.guang5@zte.com.cn>

coccinelle report:
./drivers/video/fbdev/core/fbcon.c:2680:8-16:
WARNING: use scnprintf or sprintf
./drivers/video/fbdev/core/fbcon.c:2655:8-16:
WARNING: use scnprintf or sprintf

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
