lsm: clean up redundant NULL pointer check
The implements of {ip,tcp,udp,dccp,sctp,ipv6}_hdr(skb) guarantee that they will never return NULL, and elsewhere users don't do the check as well, so remove the check here. Signed-off-by: Xiu Jianfeng <xiujianfeng@huawei.com> [PM: subject line tweaks] Signed-off-by: Paul Moore <paul@paul-moore.com>
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.
