ftrace/nds32: Update the proto for ftrace_trace_function to match ftrace_stub

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) | ^~ Link: https://lore.kernel.org/all/20211027055554.19372-1-rdunlap@infradead.org/ Link: https://lkml.kernel.org/r/20211027125101.33449969@gandalf.local.home Cc: Ingo Molnar <mingo@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Nick Hu <nickhu@andestech.com> Cc: Greentime Hu <green.hu@gmail.com> Cc: Vincent Chen <deanbo422@gmail.com> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: stable@vger.kernel.org Fixes: d19ad0775dcd6 ("ftrace: Have the callbacks receive a struct ftrace_regs instead of pt_regs") Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
