3.6.11.7-rc1 stable review patch. If anyone has any objections, please let me know. ------------------ From: Jiang Liu [ Upstream commit 343df771e671d821478dd3ef525a0610b808dbf8 ] After calling device_register(&bridge->dev), the bridge is reference- counted, and it is illegal to call kfree() on it except in the release function.
