[PATCH] platform/x86: lg-laptop: replace snprintf in show functions with sysfs_emit

[cgel . zte]

From: Ye Guojin <ye.guojin@xxxxxxxxxx>

coccicheck complains about the use of snprintf() in sysfs show
functions:
WARNING  use scnprintf or sprintf

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
