From e2bb9fab08cbcc7922050c7eb0bd650807abfa4e Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Thu, 26 Aug 2021 08:32:38 -0700 Subject: perf/x86/intel/uncore: Fix invalid unit check The uncore unit with the type ID 0 and the unit ID 0 is missed. The table3 of the uncore unit maybe 0. The uncore_discovery_invalid_unit() mistakenly treated it as an invalid value. Remove the !unit.table3 check.
