Subject: [PATCH v3 05/13] genirq: Let purely flow-masked ONESHOT irqs through unmask_threaded_irq()
Date: Tue, 29 Jun 2021 13:50:02 +0100	[thread overview]
Message-ID: <20210629125010.458872-6-valentin.schneider@arm.com> (raw)
In-Reply-To: <20210629125010.458872-1-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().
