Use DEVICE_ATTR_RW for read-write 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> @rw@ declarer name DEVICE_ATTR; identifier x,x_show,x_store; @@ DEVICE_ATTR(x, \(0644\|S_IRUGO|S_IWUSR\), x_show, x_store); @script:ocaml@ x << rw.x; x_show << rw.x_show; x_store << rw.x_store; @@ if not (x^"_show" = x_show && x^"_store" = x_store) then Coccilib.include_match false @@ declarer name DEVICE_ATTR_RW; identifier rw.x,rw.x_show,rw.x_store; @@ - DEVICE_ATTR(x, \(0644\|S_IRUGO|S_IWUSR\), x_show, x_store); + DEVICE_ATTR_RW(x); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/usb/wusbcore/wusbhc.c | 13 +++++-------- 1 file changed, 5 insertions(+), 8 deletions(-) diff --git a/drivers/usb/wusbcore/wusbhc.c b/drivers/usb/wusbcore/wusbhc.c index 94f401a..a273a91 100644 --- a/drivers/usb/wusbcore/wusbhc.c +++ b/drivers/usb/wusbcore/wusbhc.c @@ -84,8 +84,7 @@ static ssize_t wusb_trust_timeout_store(struct device *dev, out: return result < 0 ? result : size; } -static DEVICE_ATTR(wusb_trust_timeout, 0644, wusb_trust_timeout_show, - wusb_trust_timeout_store); +static DEVICE_ATTR_RW(wusb_trust_timeout); /* * Show the current WUSB CHID. @@ -145,7 +144,7 @@ static ssize_t wusb_chid_store(struct device *dev, result = wusbhc_chid_set(wusbhc, &chid); return result < 0 ? result : size; } -static DEVICE_ATTR(wusb_chid, 0644, wusb_chid_show, wusb_chid_store); +static DEVICE_ATTR_RW(wusb_chid); static ssize_t wusb_phy_rate_show(struct device *dev, @@ -174,8 +173,7 @@ static ssize_t wusb_phy_rate_store(struct device *dev, wusbhc->phy_rate = phy_rate; return size; } -static DEVICE_ATTR(wusb_phy_rate, 0644, wusb_phy_rate_show, - wusb_phy_rate_store); +static DEVICE_ATTR_RW(wusb_phy_rate); static ssize_t wusb_dnts_show(struct device *dev, struct device_attribute *attr, @@ -205,7 +203,7 @@ static ssize_t wusb_dnts_store(struct device *dev, return size; } -static DEVICE_ATTR(wusb_dnts, 0644, wusb_dnts_show, wusb_dnts_store); +static DEVICE_ATTR_RW(wusb_dnts); static ssize_t wusb_retry_count_show(struct device *dev, struct device_attribute *attr, @@ -234,8 +232,7 @@ static ssize_t wusb_retry_count_store(struct device *dev, return size; } -static DEVICE_ATTR(wusb_retry_count, 0644, wusb_retry_count_show, - wusb_retry_count_store); +static DEVICE_ATTR_RW(wusb_retry_count); /* Group all the WUSBHC attributes */ static struct attribute *wusbhc_attrs[] = { -- 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
