[PATCH v8 01/15] perf/x86/intel: Fix the comment about guest LBR support on KVM

From: Yang Weijiang
Date: Tue Aug 24 2021 - 03:41:06 EST

From: Like Xu <like.xu@xxxxxxxxxxxxxxx>

Starting from v5.12, KVM reports guest LBR and extra_regs support
when the host has relevant support. Just delete this part of the
comment and fix a typo incidentally.
