    topology: Fix compilation warning when not in SMP · ed04ce19
    Vincent Stehlé authored
    commit 53974e06603977f348ed978d75c426b0532daa67 upstream.
    The topology_##name() macro does not use its argument when CONFIG_SMP is not
    set, as it ultimately calls the cpu_data() macro.
    So we avoid maintaining a possibly unused `cpu' variable, to avoid the
    following compilation warning:
      drivers/base/topology.c: In function ‘show_physical_package_id’:
      drivers/base/topology.c:103:118: warning: unused variable ‘cpu’ [-Wunused-variable]
      drivers/base/topology.c: In function ‘show_core_id’:
      drivers/base/topology.c:106:106: warning: unused variable ‘cpu’ [-Wunused-variable]
    This can be seen with e.g. x86 defconfig and CONFIG_SMP not set.
