Subject: [PATCH] x86/pci: Annotate 'pci_root_ops' with __ro_after_init
Date: Mon, 5 Nov 2018 12:17:35 -0800 [thread overview]
Message-ID: <20181105201735.72026-1-zsm@chromium.org> (raw)
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.
