Use DEVICE_ATTR_RO etc. for read only attributes etc. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The semantic patch for the RO case, in the case where the show function already has the expected name, is as follows: (http://coccinelle.lip6.fr/) // <smpl> @ro@ declarer name DEVICE_ATTR; identifier x,x_show; @@ DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL); @script:ocaml@ x << ro.x; x_show << ro.x_show; @@ if not (x^"_show" = x_show) then Coccilib.include_match false @@ declarer name DEVICE_ATTR_RO; identifier ro.x,ro.x_show; @@ - DEVICE_ATTR(x, \(0444\|S_IRUGO\), x_show, NULL); + DEVICE_ATTR_RO(x); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/hwmon/lm95234.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/drivers/hwmon/lm95234.c b/drivers/hwmon/lm95234.c index 8796de3..c7fcc9e 100644 --- a/drivers/hwmon/lm95234.c +++ b/drivers/hwmon/lm95234.c @@ -450,8 +450,8 @@ static ssize_t set_offset(struct device *dev, struct device_attribute *attr, return count; } -static ssize_t show_interval(struct device *dev, struct device_attribute *attr, - char *buf) +static ssize_t update_interval_show(struct device *dev, + struct device_attribute *attr, char *buf) { struct lm95234_data *data = dev_get_drvdata(dev); int ret = lm95234_update_device(data); @@ -463,8 +463,9 @@ static ssize_t show_interval(struct device *dev, struct device_attribute *attr, DIV_ROUND_CLOSEST(data->interval * 1000, HZ)); } -static ssize_t set_interval(struct device *dev, struct device_attribute *attr, - const char *buf, size_t count) +static ssize_t update_interval_store(struct device *dev, + struct device_attribute *attr, + const char *buf, size_t count) { struct lm95234_data *data = dev_get_drvdata(dev); int ret = lm95234_update_device(data); @@ -566,8 +567,7 @@ static SENSOR_DEVICE_ATTR(temp4_offset, S_IWUSR | S_IRUGO, show_offset, static SENSOR_DEVICE_ATTR(temp5_offset, S_IWUSR | S_IRUGO, show_offset, set_offset, 3); -static DEVICE_ATTR(update_interval, S_IWUSR | S_IRUGO, show_interval, - set_interval); +static DEVICE_ATTR_RW(update_interval); static struct attribute *lm95234_common_attrs[] = { &sensor_dev_attr_temp1_input.dev_attr.attr, -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
