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/via-cputemp.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/drivers/hwmon/via-cputemp.c b/drivers/hwmon/via-cputemp.c index d1f209a..07a0cb0 100644 --- a/drivers/hwmon/via-cputemp.c +++ b/drivers/hwmon/via-cputemp.c @@ -88,8 +88,8 @@ static ssize_t show_temp(struct device *dev, return sprintf(buf, "%lu\n", ((unsigned long)eax & 0xffffff) * 1000); } -static ssize_t show_cpu_vid(struct device *dev, - struct device_attribute *devattr, char *buf) +static ssize_t cpu0_vid_show(struct device *dev, + struct device_attribute *devattr, char *buf) { struct via_cputemp_data *data = dev_get_drvdata(dev); u32 eax, edx; @@ -119,7 +119,7 @@ static SENSOR_DEVICE_ATTR(temp1_input, S_IRUGO, show_temp, NULL, }; /* Optional attributes */ -static DEVICE_ATTR(cpu0_vid, S_IRUGO, show_cpu_vid, NULL); +static DEVICE_ATTR_RO(cpu0_vid); static int via_cputemp_probe(struct platform_device *pdev) { -- 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
