[ Upstream commitb0350d51f0] gre_parse_header stops parsing when csum_err is encountered, which means tpi->key is undefined and ip_tunnel_lookup will return NULL improperly. This patch introduce a NULL pointer as csum_err parameter. Even when csum_err is encountered, it won't return error and continue parsing gre header as expected. Fixes:9f57c67c37("gre: Remove support for sharing GRE protocol hook.")

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.
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.
