    Subject[PATCH 5.15 323/917] perf/x86/intel/uncore: Fix Intel SPR CHA event constraints
    Date
    From: Kan Liang <kan.liang@linux.intel.com>

    [ Upstream commit 9d756e408e080d40e7916484b00c802026e6d1ad ]

    SPR CHA events have the exact same event constraints as SKX, so add the
    constraints.

    Fixes: 949b11381f81 ("perf/x86/intel/uncore: Add Sapphire Rapids server CHA support")
