Subject: [PATCH] ata: replace snprintf in show functions with sysfs_emit
Date: Tue, 12 Oct 2021 20:25:04 -0700 [thread overview]
Message-ID: <1634095505-3849-1-git-send-email-wangqing@vivo.com> (raw)
coccicheck complains about the use of snprintf() in sysfs show functions.
Fix the following coccicheck warning:
drivers/ata/libata-sata.c:830:8-16: WARNING: use scnprintf or sprintf.
Use sysfs_emit instead of scnprintf or sprintf makes more sense.
