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 <csmanjuvijay@gmail.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
