From b5ef3f2a8074af7aef9a32f4535c57f986364a60 Mon Sep 17 00:00:00 2001 From: Nicolin Chen Date: Tue, 29 Oct 2013 17:06:27 +0800 Subject: [PATCH] ASoC: wm8962: Fix null pointer pdata access in I2C probe() When using DT binding to pass private data, there would be Kernel panic occuring due to NULL pointer access in wm8962_i2c_probe(). Thus fix it.
