Subject: [PATCH 2/3] regulator: s5m8767: Fix using wrong dev argument at various places
Date: Wed, 06 Feb 2013 10:56:52 +0800 [thread overview]
Message-ID: <1360119412.8965.3.camel@phoenix> (raw)
In-Reply-To: <1360119305.8965.1.camel@phoenix>
Use &pdev->dev rather than iodev->dev for dev_err(), dev_warn() and dev_info().
Use &pdev->dev rather than iodev->dev for devm_kzalloc() and
of_get_regulator_init_data(), this fixes memory leak.
