Based on the following report from Smatch, fix the potential NULL
pointer dereference check.
tools/perf/builtin-trace.c:1044
thread_trace__new() error: we previously assumed 'ttrace' could be
null (see line 1041).
tools/perf/builtin-trace.c
1037 static struct thread_trace *thread_trace__new(void)
1038 {
1039 struct thread_trace *ttrace = zalloc(sizeof(struct thread_trace));
1040
1041 if (ttrace)
1042 ttrace->files.max = -1;
1043
1044 ttrace->syscall_stats = intlist__new(NULL);
^^^^^^^^

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.
