Subject: [PATCH V4 7/9] ARM: vt8500: Provide regulator to pwm-backlight
Date: Tue, 19 Mar 2013 11:59:31 -0700 [thread overview]
Message-ID: <1363719573-20926-8-git-send-email-achew@nvidia.com> (raw)
In-Reply-To: <1363719573-20926-1-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.
Signed-off-by: Andrew Chew <achew-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
