From c5d44423d55e3abca7b1d544af9e4c97ec203999 Mon Sep 17 00:00:00 2001 From: Travis Place Date: Mon, 25 Aug 2008 08:11:50 +0200 Subject: ALSA: CA0106 on MSI K8N Diamond PLUS Motherboard Correct a previous patch for the ca0106 onboard the MSI K8N Diamond PLUS motherboard. Confirmed to have Line/Mic/Aux working for input, and sound output working as expected.

Instead it is freed in the i2c device probe function's error path. However the success or failure of both functions is not linked, so this could result in a double free (if the platform device is successfully probed, the i2c device probing fails and then the platform driver is unregistered.) * codec->private_data is allocated in many platform device probe functions but not freed in their error paths. This patch hopefully solves all these problems.
