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. Signed-off-by: Qing Wang <wangqing@vivo.com> --- drivers/clk/clk-si5341.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-)
