From f2f0945e356daef87cdb01c0302801fb11cf382a Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 28 Sep 2012 23:36:14 +0200 Subject: tty/console: fix warnings in drivers/tty/serial/kgdboc.c The con_debug_leave/con_debug_enter functions are stubbed out by defining them to (0), which causes harmless build warnings. Using proper inline functions is the normal way to deal with this. Without this patch, building the ARM bcm2835_defconfig results in: drivers/tty/serial/kgdboc.c: In function 'kgdboc_pre_exp_handler': drivers/tty/serial/kgdboc.c:279:3: warning: statement with no effect [-Wunused-value] drivers/tty/serial/kgdboc.c: In function 'kgdboc_post_exp_handler': drivers/tty/serial/kgdboc.c:293:3: warning: statement with no effect [-Wunused-value] Signed-off-by: Arnd Bergmann Cc: Anton Vorontsov Cc: Greg Kroah-Hartman Signed-off-by: Jason Wessel --- include/linux/console.h | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'include/linux') diff --git a/include/linux/console.h b/include/linux/console.h index 7201ce4280ca..dedb082fe50f 100644 --- a/include/linux/console.h +++ b/include/linux/console.h @@ -83,8 +83,14 @@ void give_up_console(const struct consw *sw); int con_debug_enter(struct vc_data *vc); int con_debug_leave(void); #else -#define con_debug_enter(vc) (0) -#define con_debug_leave() (0) +static inline int con_debug_enter(struct vc_data *vc) +{ + return 0; +} +static inline int con_debug_leave(void) +{ + return 0; +} #endif /* scroll */ -- cgit v1.2.3
