Subject: [PATCH V6 4/9] ARM: EXYNOS: Provide regulator to pwm-backlight
Date: Mon, 1 Apr 2013 14:53:23 -0700 [thread overview]
Message-ID: <1364853208-32503-5-git-send-email-achew@nvidia.com> (raw)
In-Reply-To: <1364853208-32503-1-git-send-email-achew-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
The pwm-backlight driver now takes a mandatory regulator that is gotten
during driver probe. Initialize a dummy regulator to satisfy this
requirement.
