Subject: [PATCH AUTOSEL 4.9 04/17] video: fbdev: omapfb: acx565akm: replace snprintf with sysfs_emit

From: Yang Guang <yang.guang5@....com.cn>

[ Upstream commit 24565bc4115961db7ee64fcc7ad2a7437c0d0a49 ]

coccinelle report:
./drivers/video/fbdev/omap2/omapfb/displays/panel-sony-acx565akm.c:
479:9-17: WARNING: use scnprintf or sprintf

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
