Rob Herring c55327bc37 arm_pmu: Validate single/group leader events ... commit e5c23779f9 upstream. In the case where there is only a cycle counter available (i.e. PMCR_EL0.N is 0) and an event other than CPU cycles is opened, the open should fail as the event can never possibly be scheduled. However, the event validation when an event is opened is skipped when the group leader is opened. Fix this by always validating the group leader events.
