Ian Rogers 6ec9503f45 perf parse-events: Avoid string for PE_BP_COLON, PE_BP_SLASH
There's no need to read the string ':' or '/' for PE_BP_COLON or
PE_BP_SLASH and doing so causes parse-events.y to leak memory.

The original patch has a committer note about not using these tokens
presumably as yacc spotted they were a memory leak because no
%destructor could be run. Remove the unused token workaround as there
is now no value associated with these tokens.

Fixes: f0617f526c ("perf parse: Allow config terms with breakpoints")

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.
