coccicheck complains about the use of snprintf() in sysfs show functions. Fix the following coccicheck warning: drivers/bus/mhi/core/init.c:97:8-16: WARNING: use scnprintf or sprintf. Use sysfs_emit instead of scnprintf or sprintf makes more sense. Signed-off-by: Qing Wang <wangqing@vivo.com> --- drivers/bus/mhi/core/init.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
