Subject: [PATCH v11 03/14] irqchip/sifive-plic: Fix syscore registration for multi-socket systems
Date: Mon, 23 Oct 2023 22:57:49 +0530	[thread overview]
Message-ID: <20231023172800.315343-4-apatel@ventanamicro.com> (raw)
In-Reply-To: <20231023172800.315343-1-apatel@ventanamicro.com>

On multi-socket systems, we will have a separate PLIC in each socket
so we should register syscore operation only once for multi-socket
systems.

Fixes: e80f0b6a2cf3 ("irqchip/irq-sifive-plic: Add syscore callbacks for hibernation")
