Subject: [PATCH] irqchip/sifive-plic: Mark two global variables __ro_after_init
Date: Tue, 30 Mar 2021 02:09:11 +0800 [thread overview]
Message-ID: <20210330020911.26423e9e@xhacker> (raw)
From: Jisheng Zhang <jszhang@kernel.org>
All of these two are never modified after init, so they can be
__ro_after_init.
