Subject: [PATCH] [perf] intel_pt_recording_options: Remove redundant intel_pt_evsel null check
Date:   Tue, 23 Jun 2020 19:48:50 -0400
Message-Id: <20200623234905.18608-1-gaurav1086@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

intel_pt_evsel cannot be NULL here since its already being
dereferenced above. Remove this redundant check.
