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/gl520sm.c | 48 ++++++++++++++++++++++++------------------------ 1 file changed, 24 insertions(+), 24 deletions(-) diff --git a/drivers/hwmon/gl520sm.c b/drivers/hwmon/gl520sm.c index dee93ec..f24a614 100644 --- a/drivers/hwmon/gl520sm.c +++ b/drivers/hwmon/gl520sm.c @@ -200,13 +200,13 @@ static struct gl520_data *gl520_update_device(struct device *dev) * Sysfs stuff */ -static ssize_t get_cpu_vid(struct device *dev, struct device_attribute *attr, - char *buf) +static ssize_t cpu0_vid_show(struct device *dev, + struct device_attribute *attr, char *buf) { struct gl520_data *data = gl520_update_device(dev); return sprintf(buf, "%u\n", vid_from_reg(data->vid, data->vrm)); } -static DEVICE_ATTR(cpu0_vid, S_IRUGO, get_cpu_vid, NULL); +static DEVICE_ATTR_RO(cpu0_vid); #define VDD_FROM_REG(val) (((val) * 95 + 2) / 4) #define VDD_TO_REG(val) clamp_val((((val) * 4 + 47) / 95), 0, 255) @@ -381,8 +381,8 @@ static ssize_t get_fan_div(struct device *dev, struct device_attribute *attr, return sprintf(buf, "%d\n", DIV_FROM_REG(data->fan_div[n])); } -static ssize_t get_fan_off(struct device *dev, struct device_attribute *attr, - char *buf) +static ssize_t fan1_off_show(struct device *dev, + struct device_attribute *attr, char *buf) { struct gl520_data *data = gl520_update_device(dev); return sprintf(buf, "%d\n", data->fan_off); @@ -476,8 +476,9 @@ static ssize_t set_fan_div(struct device *dev, struct device_attribute *attr, return count; } -static ssize_t set_fan_off(struct device *dev, struct device_attribute *attr, - const char *buf, size_t count) +static ssize_t fan1_off_store(struct device *dev, + struct device_attribute *attr, const char *buf, + size_t count) { struct gl520_data *data = dev_get_drvdata(dev); struct i2c_client *client = data->client; @@ -510,8 +511,7 @@ static SENSOR_DEVICE_ATTR(fan1_div, S_IRUGO | S_IWUSR, get_fan_div, set_fan_div, 0); static SENSOR_DEVICE_ATTR(fan2_div, S_IRUGO | S_IWUSR, get_fan_div, set_fan_div, 1); -static DEVICE_ATTR(fan1_off, S_IRUGO | S_IWUSR, - get_fan_off, set_fan_off); +static DEVICE_ATTR_RW(fan1_off); #define TEMP_FROM_REG(val) (((val) - 130) * 1000) #define TEMP_TO_REG(val) clamp_val(((((val) < 0 ?
