commitb19b46346fupstream. The recent commit916c5e1413("hv/netvsc: fix handling of fallback to single queue mode") tried to fix the fallback behavior to a single queue mode, but it changed the function to return zero incorrectly, while the function should return an object pointer. Eventually this leads to a NULL dereference at the callers that expect non-NULL value. Fix it by returning the proper net_device object.

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.
