In vnet_port_probe() and vsw_port_probe(), we should check the return value of mdesc_grab() as it may return NULL which can caused NPD bugs. Fixes:5d01fa0c6b("ldmvsw: Add ldmvsw.c driver code") Fixes:43fdf27470("[SPARC64]: Abstract out mdesc accesses for better MD update handling.")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
