Hi all,

After merging the perf tree, today's linux-next build (native perf)
failed like this:

perf/util/pmu-flex.c:1812:1: error: unterminated comment
 1812 | /** Setup the input buffer state to scan a string. The next call to yylex() will
      | ^
perf/util/pmu-flex.c:550:24: error: 'yy_fatal_error' used but never defined [-Werror]
  550 | static void yynoreturn yy_fatal_error ( const char* msg , yyscan_t yyscanner );
      |                        ^~~~~~~~~~~~~~

I don't know what caused this, but the above file looks fine and redoing
the build works, so it may be some timing problem when doing an
incremental build?
