From: Lu Baolu <baolu.lu@xxxxxxxxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 71504062a7c34838c3fccd92c447f399d3cb5797 upstream. This patch fixes some wild pointers produced by xhci_mem_cleanup. These wild pointers will cause system crash if xhci_mem_cleanup() is called twice.
