Subject: [PATCH] perf/pt: Annotate pt_cap_group with __ro_after_init
Date:   Wed, 12 Sep 2018 09:45:10 -0700
Message-Id: <20180912164510.23444-1-zsm@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

pt_cap_group is written to in pt_pmu_hw_init and not modified after. This makes
it a suitable candidate for annotating as __ro_after_init.
