From 8d4124cb94c0613d79a2e3e5727b35a36497ffb7 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sat, 29 Oct 2016 21:36:57 +0200 Subject: [PATCH] wm8350_power: use permission-specific DEVICE_ATTR variants 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/) // @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); // Signed-off-by: Julia Lawall Acked-by: Charles Keepax Signed-off-by: Sebastian Reichel --- drivers/power/supply/wm8350_power.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/power/supply/wm8350_power.c b/drivers/power/supply/wm8350_power.c index 5c5880664e09..a2740cf57ad3 100644 --- a/drivers/power/supply/wm8350_power.c +++ b/drivers/power/supply/wm8350_power.c @@ -182,7 +182,7 @@ static ssize_t charger_state_show(struct device *dev, return sprintf(buf, "%s\n", charge); } -static DEVICE_ATTR(charger_state, 0444, charger_state_show, NULL); +static DEVICE_ATTR_RO(charger_state); static irqreturn_t wm8350_charger_handler(int irq, void *data) { -- 2.20.1
