[PATCH] clk-si5341: replace snprintf in show functions with sysfs_emit

From: Qing Wang
Date: Tue Oct 12 2021 - 23:26:28 EST


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

Fix the following coccicheck warning:
drivers/clk/clk-si5341.c:1471:8-16: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1486:8-16: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1501:8-16: WARNING: use scnprintf or sprintf.
drivers/clk/clk-si5341.c:1516:8-16: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
