    perf/x86/intel: Mark expected switch fall-throughs · 289a2d22
    Gustavo A. R. Silva authored
    In preparation to enabling -Wimplicit-fallthrough, mark switch
    cases where we are expecting to fall through.
    
    This patch fixes the following warnings:
    
      arch/x86/events/intel/core.c: In function ‘intel_pmu_init’:
      arch/x86/events/intel/core.c:4959:8: warning: this statement may fall through [-Wimplicit-fallthrough=]
      arch/x86/events/intel/core.c:5008:8: warning: this statement may fall through [-Wimplicit-fallthrough=]
    
    Warning level 3 was used: -Wimplicit-fallthrough=3
    
    This patch is part of the ongoing efforts to enable -Wimplicit-fallthrough.
