Date: Thu, 22 Dec 2016 13:04:47 +0100 From: Julia Lawall <Julia.Lawall@...6.fr> To: Jean Delvare <jdelvare@...e.com> Cc: kernel-janitors@...r.kernel.org, Guenter Roeck <linux@...ck-us.net>, linux-hwmon@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 18/66] hwmon: (i5k_amb) use permission-specific DEVICE_ATTR variants 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@...6.fr> --- drivers/hwmon/i5k_amb.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/hwmon/i5k_amb.c b/drivers/hwmon/i5k_amb.c index 6b3d197..a5a9f45 100644 --- a/drivers/hwmon/i5k_amb.c +++ b/drivers/hwmon/i5k_amb.c @@ -114,14 +114,14 @@ struct i5k_amb_data { unsigned int num_attrs; }; -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) { return sprintf(buf, "%s\n", DRVNAME); } -static DEVICE_ATTR(name, S_IRUGO, show_name, NULL); +static DEVICE_ATTR_RO(name); static struct platform_device *amb_pdev;
