Coccinnelle reports a warning Warning: Use scnprintf or sprintf Following the advice on kernel documentation https://www.kernel.org/doc/html/latest/filesystems/sysfs.html For show(device *...) functions we should only use sysfs_emit() or sysfs_emit_at() especially when formatting the value to be returned to user space. Convert snprintf() to sysfs_emit() Signed-off-by: Jules Irenge <jbi.octave@xxxxxxxxx> --- drivers/scsi/hptiop.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/scsi/hptiop.c b/drivers/scsi/hptiop.c index 7e8903718245..3ae4a0a8be57 100644 --- a/drivers/scsi/hptiop.c +++ b/drivers/scsi/hptiop.c @@ -1111,7 +1111,7 @@ static int hptiop_adjust_disk_queue_depth(struct scsi_device *sdev, static ssize_t hptiop_show_version(struct device *dev, struct device_attribute *attr, char *buf) { - return snprintf(buf, PAGE_SIZE, "%s\n", driver_ver); + return sysfs_emit(buf, "%s\n", driver_ver); } static ssize_t hptiop_show_fw_version(struct device *dev, @@ -1120,7 +1120,7 @@ static ssize_t hptiop_show_fw_version(struct device *dev, struct Scsi_Host *host = class_to_shost(dev); struct hptiop_hba *hba = (struct hptiop_hba *)host->hostdata; - return snprintf(buf, PAGE_SIZE, "%d.%d.%d.%d\n", + return sysfs_emit(buf, "%d.%d.%d.%d\n", hba->firmware_version >> 24, (hba->firmware_version >> 16) & 0xff, (hba->firmware_version >> 8) & 0xff, -- 2.39.2
