Subject: [PATCH 1/2] regulator: s5m8767: Fix dev argument for devm_kzalloc and of_get_regulator_init_data
Date: Wed, 13 Feb 2013 09:29:45 +0800 [thread overview]
Message-ID: <1360718985.14930.1.camel@phoenix> (raw)
Use &pdev->dev rather than iodev->dev for devm_kzalloc() and
of_get_regulator_init_data(), this fixes memory leak.
