parse_ftrace_printk() tokenizes and parses a line, calling strdup() each iteration. Add code to free this temporary format string duplicate. Fixes the following coverity complaints: Error: RESOURCE_LEAK (CWE-772): tools/perf/util/trace-event-parse.c:158: overwrite_var: Overwriting "printk" in "printk = strdup(fmt + 1)" leaks the storage that "printk" points to. tools/perf/util/trace-event-parse.c:162: leaked_storage: Variable "printk" going out of scope leaks the storage it points to.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
