From 33777f34b5cc16a9fb2cd480e7db84c8de631fde Mon Sep 17 00:00:00 2001 From: Majunath Goudar Date: Tue, 22 Oct 2013 16:00:27 -0700 Subject: [PATCH] Input: fix PWM-related undefined reference errors This patch adds a PWM dependency to configure the INPUT_MAX8997_HAPTIC and INPUT_PWM_BEEPER. Without this patch, build system can lead to build failure. This was observed during randconfig testing, in which INPUT_MAX8997_HAPTIC or INPUT_PWM_BEEPER was enabled w/o PWM being enabled, leading to the following errors: init/built-in.o drivers/built-in.o: In function `max8997_haptic_disable': :(.text+0x1073a0): undefined reference to `pwm_disable' drivers/built-in.o: In function `max8997_haptic_remove': :(.text+0x1073fc): undefined reference to `pwm_free' drivers/built-in.o: In function `max8997_haptic_play_effect_work': :(.text+0x1074f0): undefined reference to `pwm_config' :(.text+0x1075b0): undefined reference to `pwm_enable' drivers/built-in.o: In function `max8997_haptic_probe': :(.text+0x1076f8): undefined reference to `pwm_request' :(.text+0x1077e8): undefined reference to `pwm_free' drivers/built-in.o: In function `pwm_beeper_resume': :(.text+0x1081a4): undefined reference to `pwm_config' make: *** [vmlinux] Error 1 Signed-off-by: Manjunath Goudar Signed-off-by: Dmitry Torokhov --- drivers/input/misc/Kconfig | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/input/misc/Kconfig b/drivers/input/misc/Kconfig index aa51baa..5f4967d 100644 --- a/drivers/input/misc/Kconfig +++ b/drivers/input/misc/Kconfig @@ -156,7 +156,7 @@ config INPUT_MAX8925_ONKEY config INPUT_MAX8997_HAPTIC tristate "MAXIM MAX8997 haptic controller support" - depends on HAVE_PWM && MFD_MAX8997 + depends on PWM && HAVE_PWM && MFD_MAX8997 select INPUT_FF_MEMLESS help This option enables device driver support for the haptic controller @@ -461,7 +461,7 @@ config INPUT_PCF8574 config INPUT_PWM_BEEPER tristate "PWM beeper support" - depends on HAVE_PWM || PWM + depends on PWM && HAVE_PWM help Say Y here to get support for PWM based beeper devices. -- 2.7.4
