commit e406f12dde1a8375d77ea02d91f313fb1a9c6aec upstream. mddev->sync_thread can be set to NULL on kzalloc failure downstream. The patch checks for such a scenario and frees allocated resources. Committer node: Added similar fix to raid5.c, as suggested by Guoqing.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
