    Subject[PATCH AUTOSEL 5.15 09/44] powerpc/smp: Move setup_profiling_timer() under CONFIG_PROFILING
    Date
    From: Michael Ellerman <mpe@ellerman.id.au>

    [ Upstream commit a4ac0d249a5db80e79d573db9e4ad29354b643a8 ]

    setup_profiling_timer() is only needed when CONFIG_PROFILING is enabled.

    Fixes the following W=1 warning when CONFIG_PROFILING=n:
    linux/arch/powerpc/kernel/smp.c:1638:5: error: no previous prototype for ‘setup_profiling_timer’
