perf: Fix parsing of __print_flags() in TP_printk()
commit d06c27b22aa66e48e32f03f9387328a9af9b0625 upstream. A update is made to the sched:sched_switch event that adds some logic to the first parameter of the __print_flags() that shows the state of tasks. This change cause perf to fail parsing the flags. A simple fix is needed to have the parser be able to process ops within the argument.
