From: Qing Wang <wangqing@xxxxxxxx> The sysfs show() functions must not use snprintf() when formatting the value to be returned to user space. Fix the following coccicheck warning: | drivers/net/can/at91_can.c:1185: WARNING: use scnprintf or sprintf. | drivers/net/can/janz-ican3.c:1834: WARNING: use scnprintf or sprintf. | | Use sysfs_emit instead of scnprintf or sprintf makes more sense.
