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/f71882fg.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/hwmon/f71882fg.c b/drivers/hwmon/f71882fg.c index cb28e4b..ca54ce5 100644 --- a/drivers/hwmon/f71882fg.c +++ b/drivers/hwmon/f71882fg.c @@ -390,7 +390,7 @@ static ssize_t show_pwm_auto_point_temp(struct device *dev, static ssize_t store_pwm_auto_point_temp(struct device *dev, struct device_attribute *devattr, const char *buf, size_t count); /* Sysfs misc */ -static ssize_t show_name(struct device *dev, struct device_attribute *devattr, +static ssize_t name_show(struct device *dev, struct device_attribute *devattr, char *buf); static int f71882fg_probe(struct platform_device *pdev); @@ -404,7 +404,7 @@ static ssize_t show_name(struct device *dev, struct device_attribute *devattr, .remove = f71882fg_remove, }; -static DEVICE_ATTR(name, S_IRUGO, show_name, NULL); +static DEVICE_ATTR_RO(name); /* * Temp attr for the f71858fg, the f71858fg is special as it has its @@ -2212,7 +2212,7 @@ static ssize_t store_pwm_auto_point_temp(struct device *dev, return count; } -static ssize_t show_name(struct device *dev, struct device_attribute *devattr, +static ssize_t name_show(struct device *dev, struct device_attribute *devattr, char *buf) { struct f71882fg_data *data = dev_get_drvdata(dev); -- 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
