> The root port regular expression accepts trailing characters and an
> unbounded domain field. A nine-digit domain matches it but makes the
> subsequent width-limited sscanf() stop before the bus. The parser still
> returns success, allowing the filter to use an uninitialized or stale
> bus value. A three-digit bus is silently truncated as well.
>
> Match the complete notation within the documented domain and bus widths.
> Check regular expression compilation and propagate conversion failures
> instead of treating a warning as successful parsing.

> Fixes: f9ed693e8bc0 ("perf stat: Enable iostat mode for x86 platforms")
