From 4b1bf5871f7d59de6484cc887e205d6d2f1e6fbd Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Tue, 31 Jul 2012 04:39:30 -0700 Subject: [PATCH] thermal: Constify 'type' argument for the registration routine thermal_zone_device_register() does not modify 'type' argument, so it is safe to declare it as const. Otherwise, if we pass a const string, we are getting the ugly warning: CC drivers/power/power_supply_core.o drivers/power/power_supply_core.c: In function 'psy_register_thermal': drivers/power/power_supply_core.c:204:6: warning: passing argument 1 of 'thermal_zone_device_register' discards 'const' qualifier from pointer target type [enabled by default] include/linux/thermal.h:140:29: note: expected 'char *' but argument is of type 'const char *' Signed-off-by: Anton Vorontsov Acked-by: Jean Delvare --- drivers/thermal/thermal_sys.c | 2 +- include/linux/thermal.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/thermal/thermal_sys.c b/drivers/thermal/thermal_sys.c index 5feb3353213f..32aa66d7d6b3 100644 --- a/drivers/thermal/thermal_sys.c +++ b/drivers/thermal/thermal_sys.c @@ -1173,7 +1173,7 @@ static void remove_trip_attrs(struct thermal_zone_device *tz) * longer needed.
