Subject: [RFC PATCH v2 05/10] genirq: Let purely flow-masked ONESHOT irqs through unmask_threaded_irq()
Date: Tue, 25 May 2021 18:32:50 +0100 [thread overview]
Message-ID: <20210525173255.620606-6-valentin.schneider@arm.com> (raw)
In-Reply-To: <20210525173255.620606-1-valentin.schneider@arm.com>
A subsequent patch will let IRQs end up in irq_finalize_oneshot() without
IRQD_IRQ_MASKED, but with IRQD_IRQ_FLOW_MASKED set instead. Let such IRQs
receive their final ->irq_eoi().
