The ftrace callback prototype was changed to pass a special ftrace_regs
instead of pt_regs as the last parameter, but the static ftrace for nds32
missed updating ftrace_trace_function and this caused a warning when
compared to ftrace_stub:
../arch/nds32/kernel/ftrace.c: In function '_mcount':
../arch/nds32/kernel/ftrace.c:24:35: error: comparison of distinct pointer types lacks a cast [-Werror]
24 | if (ftrace_trace_function != ftrace_stub)

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.
