Subject: [PATCH 3/3] bus: mhi: replace snprintf in show functions with sysfs_emit

From: Qing Wang <>

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.
