From: achew@nvidia.com (Andrew Chew) Date: Mon, 1 Apr 2013 14:53:27 -0700 Subject: [PATCH V6 8/9] ARM: tegra: Provide regulator to pwm-backlight In-Reply-To: <1364853208-32503-1-git-send-email-achew@nvidia.com> References: <1364853208-32503-1-git-send-email-achew@nvidia.com> Message-ID: <1364853208-32503-9-git-send-email-achew@nvidia.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org The pwm-backlight driver now takes a mandatory regulator that is gotten during driver probe. Initialize a dummy regulator to satisfy this requirement.
