Subject: [PATCH 5.4 065/222] perf/x86/intel/uncore: Fix missing marker for snr_uncore_imc_freerunning_events

From: Kan Liang <kan.liang@...ux.intel.com>

commit fa694ae532836bd2f4cd659e9b4032abaf9fa9e5 upstream.

An Oops during the boot is found on some SNR machines.  It turns out
this is because the snr_uncore_imc_freerunning_events[] array was
missing an end-marker.

Fixes: ee49532b38dd ("perf/x86/intel/uncore: Add IMC uncore support for Snow Ridge")
