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/max197.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/hwmon/max197.c b/drivers/hwmon/max197.c index 0762856..638567f 100644 --- a/drivers/hwmon/max197.c +++ b/drivers/hwmon/max197.c @@ -207,8 +207,8 @@ static ssize_t max197_show_input(struct device *dev, return ret; } -static ssize_t max197_show_name(struct device *dev, - struct device_attribute *attr, char *buf) +static ssize_t name_show(struct device *dev, struct device_attribute *attr, + char *buf) { struct platform_device *pdev = to_platform_device(dev); return sprintf(buf, "%s\n", pdev->name); @@ -231,7 +231,7 @@ static ssize_t max197_show_name(struct device *dev, &sensor_dev_attr_in##chan##_max.dev_attr.attr, \ &sensor_dev_attr_in##chan##_min.dev_attr.attr -static DEVICE_ATTR(name, S_IRUGO, max197_show_name, NULL); +static DEVICE_ATTR_RO(name); MAX197_SENSOR_DEVICE_ATTR_CH(0); MAX197_SENSOR_DEVICE_ATTR_CH(1); -- 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
