From d280289e799dcdf5913e8935bffe136d7594e26d Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Mon, 1 Sep 2008 17:44:05 +0200 Subject: [PATCH] sound: ASoC: Fix an error path in neo1973_wm8753 The error handling in neo1973_init is incorrect: * If platform_device_add fails, we go on with the rest of the initialization instead of bailing out. Things will break when the module is removed (platform_device_unregister called on a device that wasn't registered.) * If i2c_add_driver fails, we return an error so the module will not load, but we don't unregister neo1973_snd_device, so we are leaking resources. Add the missing error handling.
