From: Li Zefan <lizefan@xxxxxxxxxx> 3.12-stable review patch. If anyone has any objections, please let me know. =============== 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.
