    drivers/perf: arm_pmu: make info messages more verbose · c6b90653
    Dirk Behme authored
    On a big.LITTLE system e.g. with Cortex A57 and A53 in case not all cores
    are online at PMU probe time we might get
    
    hw perfevents: failed to probe PMU!
    hw perfevents: failed to register PMU devices!
    
    making it unclear which cores failed, here.
    
    Add the device tree full name which failed and the error value resulting
    in a more verbose and helpful message like
    
    hw perfevents: /soc/pmu_a53: failed to probe PMU! Error -6
    hw perfevents: /soc/pmu_a53: failed to register PMU devices! Error -6
