Subject: [PATCH] gpio: include linux/bug.h in interface header
Date: Thu, 08 May 2014 15:42:25 +0200 [thread overview]
Message-ID: <7225229.HqAtN0I8Si@wuerfel> (raw)
Today's linux-next kernel started showing build errors for the
use of WARN_ON in linux/gpio/consumer.h:
In file included from drivers/video/backlight/pwm_bl.c:13:0:
include/linux/gpio/consumer.h: In function 'gpiod_put':
include/linux/gpio/consumer.h:81:2: error: implicit declaration of function 'WARN_ON' [-Werror=implicit-function-declaration]
It's not clear why this never happened before, but this patch
fixes it by including the header that contains the defintion
of this macro.
