    drivers/bus: arm-cci: fix build warnings · 984e9cf1
    Arnd Bergmann authored
    When the arm-cci driver is enabled, but both CONFIG_ARM_CCI5xx_PMU and
    CONFIG_ARM_CCI400_PMU are not, we get a warning about how parts of
    the driver are never used:
    
    drivers/perf/arm-cci.c:1454:29: error: 'cci_pmu_models' defined but not used [-Werror=unused-variable]
    drivers/perf/arm-cci.c:693:16: error: 'cci_pmu_event_show' defined but not used [-Werror=unused-function]
    drivers/perf/arm-cci.c:685:16: error: 'cci_pmu_format_show' defined but not used [-Werror=unused-function]
    
    Marking all three functions as __maybe_unused avoids the warnings in
    randconfig builds. I'm doing this lacking any ideas for a better fix.
