#     powerpc/papr_scm: Ensure rc is always initialized in papr_scm_pmu_register()
#     
#     Clang warns:
#     
#       arch/powerpc/platforms/pseries/papr_scm.c:492:6: warning: variable 'rc' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]

#       arch/powerpc/platforms/pseries/papr_scm.c:492:2: note: remove the 'if' if its condition is always false

#       arch/powerpc/platforms/pseries/papr_scm.c:484:8: note: initialize the variable 'rc' to silence this warning
#               int rc, nodeid;
#                     ^
#                     = 0
#       1 warning generated.
#     
#     The call to papr_scm_pmu_check_events() was eliminated but a return code
#     was not added to the if statement. Add the same return code from
#     papr_scm_pmu_check_events() for this condition so there is no more
#     warning.
