Subject: [PATCH RESEND] clk-si5341: replace snprintf in show functions with sysfs_emit
Date: Thu, 14 Oct 2021 23:45:28 -0700	[thread overview]
Message-ID: <1634280331-4150-1-git-send-email-wangqing@vivo.com> (raw)

coccicheck complains about the use of snprintf() in sysfs show functions.

Fix the following coccicheck warning:
drivers/clk/clk-si5341.c:1471: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1486: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1501: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1516: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
