Subject: [PATCH] bus: mhi: replace snprintf in show functions with sysfs_emit
Date: Tue, 12 Oct 2021 20:25:50 -0700	[thread overview]
Message-ID: <1634095550-3978-1-git-send-email-wangqing@vivo.com> (raw)

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.
