Subject: perf/x86/amd: Remove unused variable 'hwc'
X-Git-Tag: v5.19-rc1~205^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=bc469ddf67154a4840267132e87ce0d8b72d4952;p=thirdparty%2Fkernel%2Flinux.git

perf/x86/amd: Remove unused variable 'hwc'

'hwc' is never used in amd_pmu_enable_all(), so remove it.
