From a1ef7bd9fce8aba8e4701e60208148fb3bc9bdd4 Mon Sep 17 00:00:00 2001 From: Kurt Van Dijck Date: Tue, 18 Dec 2012 18:50:57 +0100 Subject: can: rename LED trigger name on netdev renames The LED trigger name for CAN devices is based on the initial CAN device name, but does never change. The LED trigger name is not guaranteed to be unique in case of hotplugging CAN devices. This patch tries to address this problem by modifying the LED trigger name according to the CAN device name when the latter changes. v1 - Kurt Van Dijck v2 - Fabio Baltieri - remove rename blocking if trigger is bound - use led-subsystem function for the actual rename (still WiP) - call init/exit functions from dev.c v3 - Kurt Van Dijck - safe operation for non-candev based devices (vcan, slcan) based on earlier patch v4 - Kurt Van Dijck - trivial patch mistakes fixed Signed-off-by: Kurt Van Dijck Signed-off-by: Fabio Baltieri Signed-off-by: Marc Kleine-Budde --- include/linux/can/led.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'include') diff --git a/include/linux/can/led.h b/include/linux/can/led.h index 12d5549abb95..9c1167baf273 100644 --- a/include/linux/can/led.h +++ b/include/linux/can/led.h @@ -26,6 +26,8 @@ enum can_led_event { void can_led_event(struct net_device *netdev, enum can_led_event event); void devm_can_led_init(struct net_device *netdev); +int __init can_led_notifier_init(void); +void __exit can_led_notifier_exit(void); #else @@ -36,6 +38,13 @@ static inline void can_led_event(struct net_device *netdev, static inline void devm_can_led_init(struct net_device *netdev) { } +static inline int can_led_notifier_init(void) +{ + return 0; +} +static inline void can_led_notifier_exit(void) +{ +} #endif -- cgit v1.2.3
