From 08337fdac215d8583770c34e7449c88947aceda8 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Thu, 24 Jan 2013 10:31:45 +0800 Subject: [PATCH] regulator: tps65910: Fix using wrong dev argument for calling of_regulator_match The dev parameter is the device requesting 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.
