3.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Li Zefan <lize...@huawei.com>
commit 3ead9578443b66ddb3d50ed4f53af8a0c0298ec5 upstream.
@wait is a local variable, so if we don't remove it from the wait queue
list, later wake_up() may end up accessing invalid memory.
This was spotted by eyes.
