Subject: [PATCH v10 08/32] ARM: GIC: export and extend vgic_init_pending_irq()
Date: Fri, 26 May 2017 18:35:16 +0100 [thread overview]
Message-ID: <20170526173540.10066-9-andre.przywara@arm.com> (raw)
In-Reply-To: <20170526173540.10066-1-andre.przywara@arm.com>
For LPIs we later want to dynamically allocate struct pending_irqs.
So beside needing to initialize the struct from there we also need
to clean it up and re-initialize it later on.
Export vgic_init_pending_irq() and extend it to be reusable.
