Subject: [PATCH] x86/pci: Annotate 'pci_root_ops' with __ro_after_init
Date:   Mon,  5 Nov 2018 12:17:35 -0800
Message-Id: <20181105201735.72026-1-zsm@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

When CONFIG_X86_INTEL_MID is set pci_root_ops is written to inside
intel_mid_pci_init(which is marked __init) and not modified after. This
makes pci_root_ops a suitable candidate for annotating as
__ro_after_init.
