From d4db89c34521a83371fd46bea34834dff128a5cf Mon Sep 17 00:00:00 2001 From: Li Zhijian Date: Mon, 22 Jan 2024 13:39:42 +0800 Subject: [PATCH] firewire: Convert snprintf/sprintf to sysfs_emit Per filesystems/sysfs.rst, show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space. coccinelle complains that there are still a couple of functions that use snprintf(). Convert them to sysfs_emit(). > drivers/firewire/core-device.c:326:8-16: WARNING: please use sysfs_emit or sysfs_emit_at No functional change intended Signed-off-by: Li Zhijian Link: https://lore.kernel.org/r/20240122053942.80648-2-lizhijian@fujitsu.com Signed-off-by: Takashi Sakamoto --- drivers/firewire/core-device.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/firewire/core-device.c b/drivers/firewire/core-device.c index 3a1a2bf1717c..a802c6d4f4fd 100644 --- a/drivers/firewire/core-device.c +++ b/drivers/firewire/core-device.c @@ -322,7 +322,7 @@ static ssize_t show_immediate(struct device *dev, if (value < 0) return -ENOENT; - return snprintf(buf, PAGE_SIZE, "0x%06x\n", value); + return sysfs_emit(buf, "0x%06x\n", value); } #define IMMEDIATE_ATTR(name, key) \ @@ -482,7 +482,7 @@ static ssize_t is_local_show(struct device *dev, { struct fw_device *device = fw_device(dev); - return sprintf(buf, "%u\n", device->is_local); + return sysfs_emit(buf, "%u\n", device->is_local); } static int units_sprintf(char *buf, const u32 *directory)
