Use DEVICE_ATTR_RO for read only attributes. This simplifies the source code, improves readbility, and reduces the chance of inconsistencies. The semantic patch that makes this change 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/tty/nozomi.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/tty/nozomi.c b/drivers/tty/nozomi.c index d6fd0e8..e2020a6 100644 --- a/drivers/tty/nozomi.c +++ b/drivers/tty/nozomi.c @@ -1320,7 +1320,7 @@ static ssize_t card_type_show(struct device *dev, struct device_attribute *attr, return sprintf(buf, "%d\n", dc->card_type); } -static DEVICE_ATTR(card_type, S_IRUGO, card_type_show, NULL); +static DEVICE_ATTR_RO(card_type); static ssize_t open_ttys_show(struct device *dev, struct device_attribute *attr, char *buf) @@ -1329,7 +1329,7 @@ static ssize_t open_ttys_show(struct device *dev, struct device_attribute *attr, return sprintf(buf, "%u\n", dc->open_ttys); } -static DEVICE_ATTR(open_ttys, S_IRUGO, open_ttys_show, NULL); +static DEVICE_ATTR_RO(open_ttys); static void make_sysfs_files(struct nozomi *dc) { -- 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
