Subject: [PATCH 1/2] regulator: tps65217: Fix using wrong dev argument for calling of_regulator_match
Date: Thu, 24 Jan 2013 10:27:30 +0800	[thread overview]
Message-ID: <1358994450.20257.1.camel@phoenix> (raw)

The dev parameter is the device requestiong the data.
In this case it should be &pdev->dev rather than pdev->dev.parent.

The dev parameter is used to call devm_kzalloc in of_get_regulator_init_data(),
which means this fixes a memory leak because the memory is allocated every time
probe() is called, thus it should be freed when this driver is unloaded.
