Subject: [PATCH 12/13] video/backlight: LP855X needs PWM
Date: Thu, 24 Apr 2014 12:28:28 +0000 [thread overview]
Message-ID: <1398342509-10243-13-git-send-email-peter.griffin@linaro.org> (raw)
In-Reply-To: <1398342509-10243-1-git-send-email-peter.griffin@linaro.org>
From: Arnd Bergmann <arnd@arndb.de>
The LP855X driver cannot be successfully built if we don't
enable the PWM subsystem. This patch makes that dependency
explicit in Kconfig and prevents broken randconfig builds.
