I can't imagine when or why `current' would return a NULL pointer. This
check was added in commit
72829bc3d6 ("ftrace: move enums to ftrace.h and make helper function global")
but it doesn't give me hint why it was needed.
Assume `current' never returns a NULL pointer and remove the check.

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.
